Abstract
A dual-loop eight-channel electrocardiogram (ECG)
recording system with the fast settling mode is proposed for
wireless real-time 12-lead ECG applications. It employs the fre-
quency division multiplexing (FDM) technique to achieve multi-
channel IA (MCIA). The FDM technique allows using smaller
input capacitor and sharing of programmable gain amplifier
(PGA), buffer, and ADC to achieve smaller area. To suppress
the dc offset of bio-signal with faster settling, dual dc servo
loops are proposed. T
