Abstract :
Biquad sections are the basic building block of practical switched-capacitor (SC) filters. The authors focus on the amenability of various biquad options for high-frequency operation. A comparison on the basis of analysis and a recent nonideal SC network simulation tool are confirmed by results from a VLSI 1.25-μm CMOS test chip. A differencing-input SC biquad is shown to have a significant performance advantage over other circuits.
