An isolation driver circuit for a pulse width modulation signal. The isolation driver circuit includes a rising edge detection circuit, a falling edge detection circuit, and a decoder. The rising edge detection circuit and the falling edge detection circuit respectively detect rising edges and falling edges of the input pulse width modulation signal, and respectively output corresponding rising edge detection signals and falling edge detection signals that are capacitively isolated from the input pulse width modulation signal. The decoder receives the rising edge detection signals and the falling edge detection signals, and outputs respective rising edges and falling edges of an output pulse width modulation signal that temporally align with the respective rising edges and falling edges of the input pulse width modulation signal. Thus, information stored in the pulse widths of the input pulse width modulation signal are preserved with high fidelity in the output pulse width modulation signal.
