Abstract
This paper presents an electrocardiogram amplifier with operational transconductance amplifier at 0.18 µm. Comb active filters are used for designing of amplifier circuits and the selected frequencies are removed from various signals. The designing of filter circuit is based on only transconductance amplifiers and capacitors are very suitable for implementation of ICs. Different ECG signals 60, 180, 300 and 420 Hz is applied to the analog circuits’ know the working capability of analog circuits. Different ECG parameters are measured with the help of cadence Virtuoso tool, this tool is analog design environment, the performance parameters are bandwidth and gain increases for an increase in bias current.
