In this paper, a three-stage ultra-low power and lowvoltage operational transconductance amplifier (OTA) was designed using transistors in sub-threshold region.Abstract:
A three-stage ultra-low power and low-voltage operational transconductance amplifier (OTA) has been designed using transistors in sub-threshold region. Simulation for 45-nm CMOS technology and a supply voltage of 250 mV yields a DC gain of 66.074dB, phase margin of 64.9° and power consumption of 1.84nW showing its suitability for biomedical application.read more
