To the best of our knowledge, these behavioural models are the most accurate and thorough models reported to date, taking into account not only small-signal effects but also other important large-signal phenomena. You can track your delivery by going to and entering your tracking number - your Order Shipped email will contain this information for each parcel. Sub- sequently, pipeline converters will be introduced in Sect. As can be inferred, the three basic components in this design procedure are the behavioural simulator, the Matlab routines and the optimization algorithm. Models described in this book accurately predict transient behaviors, which are key to the performance of discrete-time systems and hence to the performance of pipeline data converters. If this distance is kept constant between all discrete amplitudes, it is said that a uniform quantization is employed. Relatively short computation times are required, although the accuracy of the results depends on these equations.
Since the number of bits to solve per stage is generally lower than 4—5 bits, flash architectures are commonly used. The circuit noise is therefore folded back several times in base band aliasing, increasing the power noise considerably and limiting the res- olution of the circuit. Tracking delivery Saver Delivery: Australia post Australia Post deliveries can be tracked on route with eParcel. If your order has not yet been shipped you will need to send Dymocks Online an email advising the error and requesting a change in details. After this, the final design is stored in a database and a new entry, which includes the most salient features of the converter power consumption, effective resolution, etc.
Let us explain the top-down design methodology in Fig. This would simplify the design of a pipeline converter considerably. Please be aware that the delivery time frame may vary according to the area of delivery and due to various reasons, the delivery may take longer than the original estimated timeframe. Dispatch time The time it takes to verify the order, complete invoicing, prepare your item s and dispatch. The test procedure and the measured performance will be presented and compared with similar state-of-the-art pipeline converters in this chapter. The book is organized into seven chapters.
The topology selection will depend on the requirements and application. Pages 105-170 Experimental Results and State of the Art. Brief descriptions will be offered for thex Preface basic components, that is, the behavioural simulator, the set of Matlab routines and the optimizer. These key elements will be discussed in the next section. Furthermore, thermal noise acquires greater importance in data converters due to the sampling process. If we need to do this there is no extra charge to you. This will be followed by an explanation of the tools required and needs for supporting the top-down design methodology.
As will be shown in the next chapter, these behavioural models present excellent agreement with the electrical results, so accuracy is guaranteed. The high-level converter specifications will be directly mapped to transistor-level specifications, verifying target fulfilment by means of transistor-level simulations. Reshipping: If your order is returned to us by the delivery company due to incorrect or insufficient delivery details, you will be charged the cost of reshipping the order. Models described in this book accurately predict transient behaviors, which are key to the performance of discrete-time systems and hence to the performance of pipeline data converters. We will then contact you with the appropriate action.
The starting point is provided by the converter specifications, i. As the final step of the conventional design methodology, the layout of the basic building blocks is carried out. The design of these analog circuits is a major challenge for designers due to rapidly-evolving digital systems, which require increasingly accurate and fast converters, while the current trend to integrate them into adverse digital technologies is also a contributing factor. Note that a physical-level knowledge of the basic building blocks is crucial for the understanding of the main error mechanisms which degrade the converter performance, as will be shown in Chap. Next, these high-level specifications must be translated onto transistor level low- level specifications mapping.
These models are capable of capturing and predicting the behavior of pipeline data converters within less than half-a-bit deviation, versus transistor-level simulations. A circuit level, where the basic building blocks are described in greater detail using simple and efficient models which take into account the major non-idealities of the actual circuit implementation. Please note that some countries may charge the recipient duties on the 'import' of parcels from time-to-time. In summary, the opamp sharing technique has a high potential to reduce the power consumption of pipeline converters but some drawbacks are still to be overcome. Printed on acid-free paper Springer is part of Springer ScienceBusiness Media www. Therefore, the analog signal could be recon- structed from these samples without loss of information.
In accordance with these converter specifications, a database of feasible converter candidates is generated. The advantage afforded by this is that the number of amplifiers required is halved and power consumption is significantly reduced. It acts as performance evaluator within the synthesis pro- cedure. The limited dynamics of the real circuits can also cause a settling error which makes it impossible to achieve the final output value required in the time available. Then, using an iterative pro- cedure for each candidate, the optimization algorithm will try to find the values for certain design variables which satisfy these high-level specifications with minimum power consumption and silicon area. This increases the converter complexity as well as the power consumption.
This leads to the output voltages summarized in Table 1. Problems with your delivery In the event that the courier company fails to deliver your order due to invalid address information, they will return the order back to Dymocks Online. One of the most common approaches is what is known as the top-down design methodology, where the converter design is split into several abstraction levels. The main disadvantage of a regenerative comparator is its high sensitivity to mismatch, which translates into a high offset. Describes efficient procedures for heirarchical top-down design of pipeline converters; Presents new methodologies to reduce bottom-up iterations, through inherent embedding of transistor-level parameters, such as parasitic capacitances, transconductances, and saturation currents; Provides mathematical details of behavioral models, includes descriptions of the synthesis methods and associated tools and illustrates models through case studies supported by silicon prototypes. The layouts of all basic building blocks will be presented and post-layout verifications will be carried out. Depending on the nature of the characterization, it is possible to distinguish two main categories of metrics those which characterize static performance and those which determine dynamic performance.
