A CMOS nested-chopper instrumentation amplifier with 100
... The main characteristic of the autozero technique and its derivatives is that the offset cancellation is done in two phases. A samwhen the offset is measured and sampled on pling phase and an amplification phase when the sampled offset is subtracted from the input signal and amplified. This techniqu ...
