Abstract
A Direct Current (DC) coupled analog front end for an electrocardiogram (ECG) measuring device is provided that includes an amplifying stage including a first op-amp that is configured to receive a signal input from an ECG patch at a first input port and a feedback signal at a second input port and to produce an amplified output of an ECG signal via a first output port; a feedback stage including a second op-amp that is configured to receive the amplified output and produce the feedback signal at a second output port; and a DC source, coupled between the signal input from the ECG patch and the first input port.
