1. A device, comprising:
a first electronic side;
a second electronic side;
an isolation barrier galvanically isolating the first electronic side and the second electronic side from one another, the isolation barrier including a signal coupler configured to enable signaling between the first and second electronic sides over the isolation barrier via electromagnetic coupling; and
transceiver circuitry included in both the first and second electronic sides and configured to implement, based on a frequency response profile of the isolation barrier, full-duplex communication between the first and second electronic sides using the same signal coupler,
wherein the second electronic side includes a gate driver for a power transistor,
wherein the first electronic side includes control circuitry for the gate driver,
wherein the transceiver circuitry is configured to simultaneously transmit a modulation signal from the first electronic side to the second electronic side and a telemetry signal from the second electronic side to the first electronic side using the same signal coupler and based on the frequency response profile of the isolation barrier.
