Design of oscillator for PWM controller

摘要：

An oscillator is designed for PWM controller chip. The resistance Rt and capacitance Ct for oscillator are located outside the chip to adjust the frequency expediently. The circuit is simulated by CADENCE Spectre, and the simulation results show that the frequency of the oscillator is 52.84KHz (at Vcc=15V), voltage stability is 0.4％. The layout is done based on the process flow and layout levels of bipolar 45V process provided by HUAYUE Microelectronics Company. The test results prove that the oscillator present in this paper meets the design requirements.
