Ripple Suppression in Capacitive-Gain Chopper Instrumentation Amplifier Using Amplifier Slicing [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2021 This paper proposes a power-up calibration scheme to mitigate the offset of a capacitive-gain chopper instrumentation amplifier (CCIA), thus suppressing the offset-induced output ripple. In this design, the first stage of the error amplifier is formed by multiple identical slices. Before normal operation, the offset polarity of each slice is determined
