T-flip-flop implementation of the universal module (signature analyzer and test generator) for built-in self-test of mixed signal circuits is proposed and analyzed.

Floating-gate analog circuits are being used to implement advanced signal processing functions and are very useful for processing analog signals prior to analog to digital conversion. We present an architecture analogous to FPGA architectures for rapid prototyping of analog signal processing systems. These systems go beyond simple programmable amplifiers and filters to include programmable and ...

In this paper, using a personal computer (PC), the practical implementation of scalar and vector control methods on a three–phase rotor surface- type permanent magnet synchronous machine drive is discussed. Based on the machine dynamic equations and the above control strategies, two block diagrams are presented first for closed-loop speed controlling of the machine drive/system. Then, the desig...

| This paper studies a family of switchedcurrent and current-mode building blocks for nonlinear sampled-data signal processing and proposes several new switched-current nonlinear circuits which can be designed using the building block approach. The proposed circuits present merits of simple circuit conguration, low voltage and low cost. The development of these circuits has not only expanded th...

This paper focuses test strategy for integrated circuits mainly mixed signal ones. The aim is the development of circuits that can help the test of integrated circuits, especially of MADBIST, in which it is necessary, a high quality analog signal easily configurable and easily integrated in silicon. These circuits can be inserted into any microprocessor or circuit, as a Core. For this system, w...

This paper describes implementation of CMOS based linear and non-linear analog circuitsusing operational trans conductance amplifier as the basic element.

In this paper we demonstrate a potential extension of formal veri cation methodology in order to deal with analog and mixed-signal circuits. In particular, we focus on verifying time-domain properties. The time-dependent behavior of an analog circuit can be described by a system of di erential algebraic equations. To analyze such circuits under all possible input signals and all values of param...
