Abstract :
This paper presents a new approach for increasing the gain of CMOS Class-E amplifier. The proposed approach is based on using dynamic threshold MOS transistor. The proposed amplifier is able to work at a low supply voltage of 1V and consumes a very small power. The proposed class-E amplifier offers very stable sinusoidal signal to drive the load. The most attractive feature of the proposed amplifier is its simple structure and is particularly interesting for biomedical devices. Simulation results for 180nm CMOS technology validate the proposed approach.
