Wide voltage range SRAM cell for low-energy using operation low power (OTA) low pass filter for ECG detection

Abstract

The main objective of the study is the low-power operational trans conductance amplifier (OTA) using the low-pass filter for portable ECG monitoring systems. To reduce overall power consumption, the electrode offset cancellation was carried out by sharing the operational transconductance amplifier (OTA) between the filter. Wide Voltage Range SRAM Cell for Low-Energy Using the design of a fourth order Butterworth low pass filter for detection. The filter strongly depends Operational Transconductance Amplifier(OTA) for implementing a Low Pass Filter. The operational transconductance amplifier (OTA) in the design of simple amplifiers with voltage-controllable gain and to the design of fourth order active filters with controllable gains and controllable critical frequencies is demonstrated.
