Abstract :
A low-power passive switched-capacitor finite-impulse response equalizer with six time-interleaved channels has been fabricated in 0.35μm CMOS. Nonlinear parasitic capacitance scales the equalized output but does not affect the zero locations of the equalizer for a binary or ternary data signal. The equalizer is fully differential with a 4-tap transfer function. The equalizer consumes 19.5 mW at 200 MS/s and occupies an active area of 1.3mm2.
