Abstract

A high-precision switched-capacitor integrator using a low-gain opamp is proposed. The circuit contains a main signal path and a predictive signal path which makes the correlated double sampling more effective. The proposed integrator was simulated using SPICE parameters for a 180 nm CMOS process with a supply voltage of 1.2 V. The circuit exhibited much lower harmonic distortion than those described in earlier works.
