Design of CMOS Crystal Oscillator with Low Power Consumption

Abstract— This work proposes a method to reduce the power consumption of Pierce crystal oscillator. This method is base on the mechanism of decreasing the clock signal amplitude. The circuit proposed in paper is designed based on XFAB 0.35μm CMOS technology to produce a 32768Hz clock signal. It operate over a supply voltage range 1.8V to 3.6V , a temperature range from -45 to 80°C. Spectre simulation results indicate that the current consumption of the crystal oscillator is only 254nA at 3V supply voltages and 27°C temperature. Performance of the crystal oscillator in corner simulations is also observed. This low power consumption oscillator will greatly extend the life of consumer electronics.

Index Terms— Pierce crystal oscillator, decrease amplitude, low power consumption.
