摘要

在本文中，我们提出了一种混合晶体振荡器，它既能实现快速启动，又能实现低稳态功耗。在启动时，通过配置皮尔斯振荡电路和多级逆变放大器实现大的负电阻，从而实现高速启动。在稳态振荡期间，振荡器被重新配置为低功耗和低相位噪声的c类互补科尔皮茨电路。原型芯片采用65nm CMOS工艺技术制造。采用穿刺式配置后，振荡器的测量启动时间和启动能量分别比未采用穿刺式配置时减少了1/11和1/5。稳定振荡时的功耗为30 μW。

A Quick Startup Low-Power Hybrid Crystal Oscillator for IoT Applications

SUMMARY In this paper, we propose a hybrid crystal oscillator which achieves both quick startup and low steady-state power consumption. At startup, a large negative resistance is realized by configuring a Pierce oscillating circuit with a multi-stage inverter amplifier, resulting in high-speed startup. During steady-state oscillation, the oscillator is reconfigured as a class-C complementary Colpitts circuit for low power consumption and low phase noise. Prototype chips were fabricated in 65nm CMOS process technology. With Pierce-type configuration, the measured startup time and startup energy of the oscillator are reduced to 1/11 and 1/5, respectively, compared with the one without Pierce-type configuration. The power consumption during steady oscillation is 30 μW.
