چکیده

This thesis describes the design of a 6-bit CMOS folding and interpolating Analog to Digital Converter (ADe). Folding and interpolating techniques can be used in CMOS flash type ADCs so that less die area and power dissipation are used. while at the same time maintaining high-speed operation. The fundamentals of the CMOS folding and interpolating circuits are covered, and some of the major design issues are reviewed and discussed. Simulation and experimental results from a 6-bit ADe test chip fabricated in a I .2um process are also presented.

A Wide Input Bandwidth 7-bit 300-MSample/s Folding and Current-Mode Interpolating ADC

A 7-bit Nyquist folding and interpolating analog-to-digital converter (ADC) that converts at 300 MSamples/s is presented. Using current-mode signal processing techniques for analog preprocessing and a front-end sample-and-hold, the proposed 7-bit folding and interpolating ADC yields a wide input bandwidth up to 60 MHz with six effective number of bits. The ADC consumes 200 mW from a 3.3-V power...

A 70 Ms / s 110 mW 8 - b CMOS folding and interpolating A / D converter

A CMOS analog to digital converter based on the folding and interpolating technique is presented. This technique is successfully applied in bipolar A/D converters and now also becomes available in CMOS technology. The analog bandwidth of the A/D converter is increased by using a transresistance amplifier at the outputs of the folding amplifiers and, due to careful circuit design, the comparator...
