Implication

New ECG amp boosts TCMRR and CMI tolerance despite mismatch; leaves open clinical validation before practice adoption.

Structured PICO

Population

Prototype chip fabricated in 180-nm CMOS for electrocardiogram (ECG) amplification

Intervention

Adaptive TCMRR enhancing loop in parallel with a charge-pump-based common-mode suppressing loop (CMSL) and fast settling technique

Outcome

Total CMRR (TCMRR), tolerance to common-mode interference (CMI), input-referred noise, and power consumption

The proposed ECG amplifier design achieves high common-mode rejection and interference tolerance with low power consumption, potentially improving robust ECG acquisition.
