The integration of data transfer and power conversion in modern electronics demands efficient methods to achieve high transmission throughput. This work presents an analog Frequency-Shift Keying (FSK) receiver for High-Frequency (HF) GaN-based talkative converters, designed to demodulate data from MHz switching noise pulses. Leveraging analog devices such as operational amplifiers, comparators, and monostables, the proposed design achieves high bit-rates, simplifies circuitry, and enhances reliability. By translating switching noise—where pulse repetition rates encode information—into logic levels, it introduces a novel and effective method for FSK demodulation in talkative converters. Addressing challenges posed by rapid pulse rates while minimizing reliance on costly digital processing components, this receiver advances beyond prior methods constrained to kHz frequencies and lower data rates. The development provides a robust and scalable solution, meeting the demands for high-speed and reliable data transfer in Power and Signal Dual Modulation (PSDM) systems.
