• This paper presents a new solution to obtain a spurs-free high precision amplifier. The method involves input chopping and correlated double sampling signal de-chopping. The offset is removed by using DC coupling. The proposed method, verified with transistor level simulations, is applied to a rail-to-rail input amplifier with 187 dB DC gain and 13.7 μA current consumption.
