This article presents a topology of a Class-D Audio Amplifier powered by a solar PhotoVotaic (PV) Cell applicable for hearing impaired patients. The amplifier is powered by a photovoltaic (PV) cell that contributes significantly in remote applications. Here a pulse width modulation (PWM) based technique has been demonstrated. Hence a simpler, power efficient, less-expensive design can be achieved. The circuit has been designed and simulated in a standard 180 nM CMOS technology to verify the efficacy of the proposed above-mentioned architecture. The THD+N is 0.016% at 3.5 KHz of the input signal switching frequency and the power efficiency is of 65% of the amplifier while the output power across 8 Ω speaker load is around 53 mW.
