CMOS integrated circuit analysis and design is a fast paced field which deals with many advanced technologies and a difficult skill for many students in a comprehensive first course in Microelectronics. New methods and techniques to help novices learn are needed. In this paper the transistor role concept is used and common individual CMOS transistor roles are identified. Typical circuit and blo...

This paper presents an analog built-in testing (BIT) architecture and its implementation. It enables the frequency response and harmonic distortion characterizations of an integrated device-under-test (DUT) through a digital off-chip interface. External analog instrumentation is avoided, reducing test time and cost. The proposed on-chip testing scheme uses a digital frequency synthesizer and a ...

In this paper a software design tool is presented that supports the designer in the development process of integrated MOS circuits. Here the general difficulty to find out the right parameter set of all devices in the circuit is split into small device-level tasks, so the designer is able to interactively compute proper W & L geometries of each single MOS-device. Starting with the common dilemm...

The human vocal tract has been successfully modeled as a series of uniform cross-section tubes concatenated end-to-end. Such a model has been part of the study of the human speech generation system for many years. The similarity of the equations for sound propagation in these tubes and transmission line equations has been exploited in articulatory speech synthesis systems. Each section of tube ...

This paper presents a circuit including a high-pass Σ∆ modulator implemented in CMOS process and a timeinterleaved high-pass Σ∆ analog to digital converter.

A low-voltage low-power analog CMOS exponential function generator is designed in 0.18μm CMOS standard technology. The proposed circuit uses Taylor’s approximation concept and consists of a linear low-voltage transconductance with two linearization techniques and one low-voltage current squarer circuit for performing this approximation method. Simulation results using HSPICE shows 60 dB-linear ...

The paper presents an analogue front-end and ADC integrated circuit for processing signals of sensors implanted into joint prosthesis. The circuit is designed to be operated with Wheatstone bridge sensors, such as strain gauges, pressure, Hall Effect, magneto-resistive sensors, etc. It performs sensor supply multiplexing, sensor signal amplification with chopper modulation, offset compensation ...

This paper discusses architectural and circuit-level aspects related to hardware realizations of fuzzy controllers. A brief overview on fuzzy inference methods is given focusing on chip implementation. The singleton or zero-order Sugeno’s method is chosen since it offers a good trade-off between hardware simplicity and control efficiency. The CMOS microcontroller described herein processes info...

Error control decoders are widely used in communication applications. Analog CMOS implementations of error control decoders may outperform digital implementations in portable applications where power is limited. However, there have been little circuit level analyses of analog decoder designs. This dissertation covers the related analog circuits in the decoder design based on the extended (8, 4)...
