Abstract
A method and apparatus for isolating voltages while transmitting data signals. In one embodiment of the method, a modulation circuit modulates a carrier signal using an input data signal. A demodulation circuit receives the modulated carrier signal via a first capacitor coupled in series between the modulation circuit and the demodulation circuit. The demodulation circuit also receives the carrier signal via a second capacitor coupled in series between the demodulation circuit and the circuit that generates the carrier signal. The demodulation circuit demodulates the modulated carrier signal using the carrier signal.
