Measured waveforms showing the active rectifier’s built-in LSK back telemetry capability through its short-coil (SC) input terminal (data signal = 500 kbps with 10% duty cycle, RL = 500 Ω, and CL = 10 μF). Data was recovered across the primary coil using a commercial RFID reader ASIC (TRF7960, Texas Instruments, Dallas, TX).
