本文提出了一种单片温度控制的OCXO应用与石英晶体直接安装在一个CMOS芯片。由于振荡器、控制器和谐振器不需要单独的PCB，因此该芯片的设计可以显著减小整个OCXO封装的尺寸。封装尺寸的减小降低了功耗（稳态时为303 mW）和预热时间（室温下为190秒）。在0 ℃ ~ 60 ℃的外部温度范围内，温度和频率稳定度分别为0.17 ℃和0.7ppm
This paper presents a one-chip temperature control for an OCXO application with a quartz crystal directly mounted on a CMOS chip. The design of this chip can reduce the size of an entire OCXO package dramatically since no separate PCBs are required for the oscillator, controller, and resonator. The reduced package size leads to less power consumption (303 mW at steady state) and a shorter warm-up time (190 seconds at room temperature). The temperature and frequency stabilities are 0.17 degC and 0.7 ppm respectively in the 0 degC to 60 degC external temperature range
