Abstract

Performance of the low-voltage and power-efficient analog-to-digital (A/D) converters, like cyclic and pipeline topologies, can be significantly enhanced by using advanced analog cores. This paper describes a careful switched capacitor (SC) architecture that can be used as a simple low-voltage implementation of the flip-around sample-and-hold (S/H) circuit. The S/H has been simulated in a 0.13μm CMOS technology featuring a signal to noise and distortion ratio (SNDR) of -75dB at 12Ms/s for a 1Vpp output voltage. Theoretical calculations and experimental results are also given to demonstrate its validity. ©2009 IEEE.
