Area and Power-Efficient Capacitively-Coupled Chopper Instrumentation Amplifiers in 28 nm CMOS for Multi-Channel Biosensing Applications

This paper presents two designs of a capacitively-coupled chopper instrumentation amplifier (CCIA) successfully implemented in 28 nm CMOS for biopotential sensing applications. The first design is a compact CCIA using offset-blocking for chopping ripple reduction, DC servo loop (DSL) for electrode o...
