摘要

为了缩短晶体振荡器(XO)的启动时间，提出了啁啾注入(CI)和负电阻升压(NRB)。通过结合CI和NRB，在180nm CMOS中测量到的39-MHz XO的启动时间从2.1ms减少到158μs，缩短了92%，是已发表的XO中最短的启动时间。测量到的电源电压变化±20%或温度变化引起的启动时间变化小于13%。

92% start-up time reduction by variation-tolerant chirp injection (CI) and negative resistance booster (NRB) in 39MHz crystal oscillator

To reduce the start-up time of a crystal oscillator (XO), a chirp injection (CI) and a negative resistance booster (NRB) are proposed. By combining CI and NRB, the measured start-up time of a 39-MHz XO in 180-nm CMOS is reduced by 92% from 2.1ms to 158μs, which is the shortest time in the published XO's. The measured start-up time variations due to the ±20% supply voltage change or the temperature change are less than 13%.
