A Fast Startup Crystal Oscillator Using Impedance Guided Chirp Injection in 22 nm FinFET CMOS
IEEE Journal of Solid-State Circuits(2022)
摘要
An Impedance Guided Chirp Injection (IGCI) oscillator-based fast startup technique is proposed in this work demonstrating startup time between 5 and 100 $\mu \text{s}$ across a wide range of oscillator frequencies. The IGCI technique can efficiently detect the resonance frequency of the crystal and provide energy injection fo...
