This work is a contribution to a drastic change in standard signal processing chains: Analog-to-Digital Converters (ADCs), digital processing circuits, Digital-to-Analog Converters (DACs)… Integrated Smart Devices and Communicating Objects are the important applications targeted by this study. The main objective is to reduce their power consumption by one or two orders of magnitude, by complete...

The present work deals with 12-bit Nyquist current-steering CMOS digital-to-analog converter (DAC) which is an essential part in baseband section of wireless transmitter circuits. Using oversampling ratio (OSR) for the proposed DAC leads to avoid use of an active analog reconstruction filter. The optimum segmentation (75%) has been used to get the best DNL and reduce glitch energy. This segment...

This paper presents MOSFET based analog to digital converter which is simple in design, has high resolution, and conversion rate better than dual slope ADC. It has no DAC which will limit the performance, no error in conversion, can operate for wide range of inputs and never become unstable. One of the industrial applications, where the proposed high resolution MOSFET ADC can be used is, for th...

Digital to analog converter is widely used mixed-signal circuit. Testing of analog and mixed signals faces lots of challenges due to the wide range of circuits and unavailability of one appropriate fault model. SAF (stuck_at_Fault), Stuck_open and stuck_short fault model at transistor level is used in this paper. Further these fault models are used to analyze the effects on the characteristics ...

A digital calibration technique for high resolution SAR ADC with only one redundant conversion bit is presented in this paper. The proposed work employs no extra calibration DAC or input signal as calibration reference. Calibration signal is generated through switching redistribution DAC in two calibration phase, so that calibration accuracy will not be affected by input signal distribution. DA...
