Class D power amplifier applies in high efficiency circuit. In hearing aid system, we require high power efficiency, low-voltage and low-power. The operation of frequency is low frequency.
All the circuits are designed based on the TSMC 035 CMOS process technology. The supply voltage is 1.5V and the input signal is 4KHz. Simulation results show that the Class D power efficiency is high efficiency amplifier. When 0.3V of 2KHz input signal is applied, The maximum THD is 0.63% and static current is 4uA and the efficiency is 83.6%.
