In mixed-signal designs, substrate coupling of digital circuit noise can severely compromise the behavior of sensitive analog circuits. Proper characterization of substrate noise is therefore indispensable. In this paper, we present an experimental setup for the characterization of directly coupled substrate noise in bulk-type CMOS. We have integrated configurable substrate noise generation and...

SystemC will become more and more important for the design of digital circuits from the specification down to the RT-Level. Complex systems often contain analog components. This paper introduces concepts for the extension of the SystemC methodology for the specification and design of analog and mixed signal systems. The concepts will be illustrated on a telecommunication system including digita...

In this paper we introduce a new subthreshold conduction CAD model for simulation of VLSI subthreshold CMOS analog circuits and systems. This model explicitly formulates the back-gate bias effect and preserves the original advantages of the existing four-parameter model while reducing the fitting parameter number down to three. A transparent relationship between the fitting parameters and the p...

This paper, split into Parts I and II, reviews recent innovations in circuit design that have accelerated the miniaturization of sensor nodes. Design techniques for key building blocks, such as sensor interfaces, timing reference, data communication, energy harvesting, and power management are reviewed. In particular, Part I introduces analog circuit techniques and sensor interfaces for miniatu...

There are plenty of methods proposed for analog electronic circuit diagnosis, but the most popular ones are the fault dictionary techniques. Admitting more cases in a fault dictionary can be seen as a natural development towards a CBR system. The proposal of this paper is to extend the fault dictionary towards a Case Based Reasoning system. The case base memory, retrieval, reuse, revise and ret...

In this report a method for the design centering of analog circuits, based on worstcase distances (WCD) is presented. In order to keep the linearization error small, only the WCDs and not the strongly nonlinear objective function itself is linearized. For the resulting nonlinear trust-region problem the generalized boundary curve (GBC) is derived as a method to determine a solution with a good ...

In this work, the state-of-the-art RF synthesis tools for non-linear RF and analog integrated circuits are discussed. Several commercial tools are compared and presented. For RF and non-linear analog circuits, due to the nonlinearity of the circuit, design optimization is not a trivial task. This paper will give an overview of the synthesis tools for RF and Analog IC, with emphasis on trade-off...

This paper presents an algorithm for training vector quantizers with an improved version of the Neural Gas model, and its implementation in analog circuitry. Theoretical properties of the algorithm are proven that clarify the performance of the method in terms of quantization quality, and motivate design aspects of the hardware implementation. The architecture for vector quantization training i...

A software program that can be considered as a tool for the fault diagnosis of analog linear circuit is presented. The proposed program implements a numerically efficient approach to identify complex ambiguity groups in the case of circuit of great size and low testability. This approach is based on an efficient QR factorization technique applied to the testability matrix. An amplifier circuit ...

This Chapter is devoted to review the static and dynamic translinear paradigm in the last years (2000-2011). Many papers have been written since then extending the application fields, proposing novel and new analog circuits and systems based on this principle, where MOS transistors are working in new regions of operation. These ongoing researches on translinear circuits arised of the requiremen...
