Capacitively-Coupled Chopper Amplifiers

As discussed in Chap. 1, capacitively coupled chopper amplifiers can potentially handle input common-mode voltages far beyond their own supplies. Furthermore, their inherent use of chopping means that they can also achieve microvolt offset and low 1/f noise.
