Abstract :
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.
