摘要

本文提出了一种用于时域ADC架构的超低功率注入锁定振荡器(ILO)电路。更具体地说，它表明，劳工组织的功耗取决于其锁定范围。研究还表明，基于ILO的移相器功耗可以通过调整其锁定范围以适应其输入的全量程来优化。电路工作在0.4V的电源电压下，功耗为500 pW，锁定范围为16 KHz。

A 500 pW 16 KHz Injection Locked Oscillator for Ultra-Low Power Time-Domain ADC Application

This paper presents an Ultra-Low Power Injection Locked Oscillator (ILO) circuit dedicated to Time-Domain ADC architectures. More particularly, it is shown that the power consumption of the ILO depends on its locking range. It is also shown that ILO based phase shifter power consumption could be optimized by adapting its locking range to the full scale of its input. The circuit works on a 0.4V supply voltage, with a 500 pW power consumption and a 16 KHz locking range.
