A Micropower Chopper—CDS Operational Amplifier [PDF]
IEEE Journal of Solid-State Circuits, 2010 A low-power spur-free precision amplifier, which uses input chopping and correlated double sampling for demodulation, is presented. This circuit employs an AC coupling between the first and the second stage that removes the first stage offset without causing ripple.
