Variation-Tolerant Quick-Start-Up CMOS Crystal Oscillator With Chirp Injection and Negative Resistance Booster

Abstract—This paper presents a variation-tolerant quick-startup 39.25 MHz crystal oscillator and a theoretical analysis of a proposed chirp injector (CI) and negative resistance booster (NRB) for the quick start up. A new analysis of the theoretical minimum start-up time provides a new criterion for evaluating the start-up time in crystal oscillators. The calculated theoretical mini
