This paper presents an ultra-low power. low cost demodulator for gaussian frequency shift keying (GFSK) receivers that use low intermediate frequencies (IF). The demodulator employs a direct IF to digital data conversion scheme by using an injection-locked ring oscillator (ILRO) with a 1-bit flip-flop. It consumes 2. https://www.lightemupsequences.com/limited-save-Custom-Congratulations-Banner-p4839-hot-choice/
