摘要

采用前馈周期控制和数字升压充电技术，研制了一种亚μ w、1周期启动的CMOS弛豫振荡器。该振荡器在90nm CMOS中实现，我们成功地演示了100kHz时钟生成，精度为±1%，功耗极低，为280nW。

A 280nW, 100kHz, 1-cycle start-up time, on-chip CMOS relaxation oscillator employing a feedforward period control scheme

A sub-μW, 1-cycle start-up CMOS relaxation oscillator has been developed with a feedforward period control scheme and a digitally-controlled boost charging technique. The oscillator is implemented in 90nm CMOS and we sucessfuly have demonstrated 100kHz clock generation with ±1%-accuracy and an extremely low power consumption of 280nW.
