A time-multiplexed switched-capacitor CDS equalizer with reduced crosstalk layout

A new time-multiplexed switched-capacitor (TM-SC) equalizer is designed on the basis of the previously reported correlated double-sampling integrator and the crosstalk reduction layout approach, which aims at improving the performance aspects on crosstalk, gain loss, 1/f noise and offset. The equalizer, which operates at a single 3-V supply and has a filter bank with 4TM channels, has been fabricated to confirm the effectiveness of the structure using a standard 0.8-/spl mu/m CMOS process.
