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.

Abstract: A microelectronic device including a galvanic isolator with filler metal within an upper isolation element. The galvanic isolator includes a lower isolation element, an upper isolation element, and an inorganic dielectric plateau between the lower isolation element and the upper isolation element. The upper isolation element contains tines of filler metal which are electrically tied to each other and are electrically tied to the upper isolation element. The ends of the tines are rounded to minimize electric fields. The filler metal increases the overall metal density on the metal layer of the upper isolation element to meet the typical metal density requirements of modern microelectronic fabrication processing.
