Design of CMOS Crystal Oscillator with Low Power Consumption
Keywords:
Pierce crystal oscillator, decrease amplitude, 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.
