Chopping amplifier

WebSouthern Illinois University Edwardsville SIUE WebThe chopper-stabilized approach uses the amplifier's input to amplitude modulate an AC carrier. This carrier, amplified and synchronously demodulated back to DC, furnishes the amplifier's output. Because the DC input is translated to and amplified as an AC signal, the amplifier's DC terms have no effect on overall drift.
