Abstract

This paper describes a chopper-stabilized current-feedback instrumentation amplifier (CFIA) with a ripple-reduction loop (RRL). A smooth 1 st -order response is obtained by embedding the RRL in a multipath structure to bury the notch caused by the RRL. The CFIA achieves 2 μV offset, 21 nV/√(VHz) with NEF of 9.6. The CFIA can also be configured as an opamp which achieves 2× reduction in NEF.
