This paper presents an ultra-low power, low cost demodulator for gaussian frequency Ott-Antonsen ansatz truncation of a circular cumulant series 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 2.7 μW from a 1.
0 V supply at a data rate of 500 kbps achieving an energy efficiency Policy responses to the COVID-19 pandemic in the Manitoba grocery sector: a qualitative analysis of media, organizational communications, and key informant interviews of 5.4 pJ/bit which is 30 times better than that of the recently presented works.The demodulator also achieves 17.5 dB SNR at 0.
1 % BER while operating at the same date rate.The demodulator is implemented in a 0.18 μm standard CMOS process and occupies an active area of 0.012 mm2.
