Design of CMOS Sawtooth Wave Oscillator for Switching Power Supply

Abstract:

Based on the CMOS technology, the sawtooth wave oscillator used in switching power supply is designed. In the condition of 27 °C and 4 V power supply voltage, the oscillation frequency of sawtooth wave oscillator is 246.61 KHz. The oscillation frequency of sawtooth wave oscillator changes between 245.94 KHz and 247.89 KHz when the power supply voltage changes between 3V and 6V. The maximum deviation is ±0.52%. From the experimental results, the sawtooth wave oscillator has good linearity, the effect of temperature and power supply to the oscillation frequency of sawtooth wave oscillator is very little. The CMOS sawtooth wave oscillator is suitable for switching power supply.
