A 1V 3.5 μW Bio-AFE With Chopper-Capacitor-Chopper Integrator-Based DSL and Low Power GM-C Filter

This brief presents a low-noise, low-power bio-signal acquisition analog front-end (Bio-AFE). It mainly includes a capacitively coupled chopper-stabilized instrumentation amplifier (CCIA), a programmable gain amplifier (PGA), a low-pass filter (LPF), and a successive approximation analog to digital...
