A chopper and auto-zero offset-stabilized CMOS instrumentation amplifier

This paper describes a CMOS instrumentation amplifier with a noise density of 42nV/νHz and 640kHz GBW at 325µA supply current. It achieves 2.5µV input offset voltage, 130dB CMRR, and 114dB PSRR by the combined use of chopping, auto-zeroing and a current-feedback topology.
