Abstract
A digital isolation circuit includes an encode circuit, a planar magnetic circuit, and a decode circuit. The encode circuit receives an input signal and divides the input signal into a first signal pulse and a second signal pulse. The planar magnetic circuit is coupled to an output of the encode circuit. The planar magnetic circuit includes a primary winding, a secondary winding and a magnetic core. The primary winding is magnetically coupled to the secondary winding through the magnetic core to generate an isolated output signal in response to the pair of signal pulses. The decode circuit receives the isolated output signal from the secondary winding to generate an output signal substantially identical to input signal. A method of digitally isolating a square wave input signal from an output signal using the digital isolation circuit is also disclosed.
