Injection Lock Frequency Divider with Class-C Coupled VCO for Nanoelectronics Harmonic Demodulator of Fluxgate Sensing

This article presents a multi-band divide-by-3 injection locked frequency divider (ILFD) and three output phases class-C voltage-controlled oscillator (VCO) to generate signal by current reused and it uses three identical single-ended current reused VCOs in a ring configuration. The proposed fluxgate magnetometer is proposed dynamic bias circuit is used to reduce the power consumption, and the back-gate BJTs in PMOSFETs are used as a phase coupling device, the circuit oscillates for nanoelectronics.
