Aimed at reducing distortion due to the threshold voltage variations of an NMOS switch,the paper introduces the design of a body effect compensated switch applicable to low voltage switched capacitor circuits.The simulation using SPICE,based on 0.5μm standard CMOS technology(V_(tno)=0.7V,V_(tpo)=1.0V) indicates that the better performance of the total harmonic distortion(THD) is attributed to the use of the designed circuit in a first-order non-inverting switched-capacitor(SC) low pass filter.
