Chopped wave stabilized amplifier

The invention relates to a chopping stabilized amplifier. A high voltage chopping stabilized amplifier may include two paths to compensate for non-ideal electrical parameters. A first path to a main input of the amplifier may include a first multiplexer interface circuit to limit a voltage at the main input of the amplifier. A second path to an auxiliary input of the amplifier may include a chopping amplifier circuit. Although there is the first multiplexer interface circuit, a transition state on the first path may excite a current in the second path that may negatively affect the signal source. Accordingly, the disclosed amplifier also includes a second multiplexer interface circuit that can decouple the second path in the transition state. The second multiplexer interface circuit is driven by a window floating comparator that is powered according to the voltages on the primary input. During a transition state, a stabilization booster circuit maintains certain nodes on the second path at a reference voltage
