A chopper amplifier with a low duty‐cycle sub‐sampling in the switched‐capacitor integrator for noise reduction
Abstract This letter presents a low‐noise implementation of the switched‐capacitor (SC) DC servo loop (DSL) in the capacitively coupled chopper instrumentation amplifier (CCIA). The noise of the SC integrator in SC DSL is first analyzed, then a low duty‐cycle subsampling and unbalanced capacitor rat...
