摘要
This letter will demonstrate the feasibility of replacing the static operational amplifiers in switched-capacitor m.o.s. circuits by a simple group of switches that acts as a dynamic amplifier.3 The method is applicable to m.o.s. and c.m.o.s. active-filter circuits such as the ladder filter and biquad, and promises to save static power and chip area by eliminating static o.a.s, as well as reducing 1/f noise. © 1979, The Institution of Electrical Engineers.
