Abstract:In this paper, two useful techniques of Dynamic Threshold Voltage MOSFET (DTMOS) and Positive FeedbackAmplifier (PFA) are investigated separately and are applied simultaneously on a Class-AB Amplifier in the 180 nm CMOS technology. In the first proposed technique, Simulation results show that operating voltage can be limited to ±0.5 V in which the voltage gain and bandwidth are 52.6 dB and 103.51 MHz, respectively. In the second proposed technique, the power consumption is reduced more than 50%, the open-loop … Show more
