Design of a 32MHz Low Temperature Drift High Precision Relaxation Oscillator
This paper describes a low-temperature drift relaxation oscillator designed based on 0.18μm CMOS technology.This relaxation type oscillator uses a metal thin film resistor and a metal insulator metal capacitor as oscillation units based on average period feedback control,and can achieve a frequency drift of 1%when the temperature changes from-40 to 125℃.
