Abstract:
Several circuits and methods for transferring an input data signal in a digital isolator are disclosed. In an embodiment, the digital isolator includes an isolation element, input circuit, and output circuit. The isolation element includes at least one input node and at least one output node, the input circuit is electronically coupled to the input node and generates modulated differential data signals based on modulating the input data signal on a carrier signal. The input circuit operates using a first supply voltage with respect to a first ground. The output circuit is electronically coupled to the output node to receive the modulated differential data signals, operates using a second supply voltage with respect to a second ground and includes a frequency-shift keying demodulator configured to generate a demodulated data signal in response to detection of presence of the carrier signal. The output circuit further generates an output data signal.

Claim (Index 11):
An output circuit for use in an isolation device, the output circuit comprising:\n a filter circuit including a filter input configured to receive a modulation signal, and a filter output configured to output a filtered modulation signal; and a demodulation circuit including:\n a switching capacitor coupled between a switch node and an output ground node; \n a first switch, coupled between the switch node and the output ground node, and controlled by a first phase signal based on the filtered modulation signal; \n a second switch, coupled between the switch node and a compensation node, and controlled by a second phase signal complementary to, and non-overlapping with, the first phase signal; \n a pull-up element coupled between an output supply node and the compensation node; \n an averaging capacitor coupled between the compensation node and the output ground node; and \n a comparator having a non-inverting input coupled to the compensation node, an inverting input coupled to a reference voltage node, and a demodulation output.
