Programmable SC Biquad Using One Single Capacitor Bank

Abstract

. an amplifier time-sharing tec hnique was propcsed to reali ze a n arbitrary number of biquadratic cells with on ly twO amplifiers. In f7]. periodical nonu niform individual samplig of each SC structure in a filter was used to prog ram SC circuits.All previous approaches used one bank of capacitors per amplifier input. In thi s paper, a new technique for programming SC circuits is
