Abstract
In this work, temperature stable pulse width modulation controller using bandgap reference voltage is proposed. Two bandgap reference voltages are designed by using BiCMOS technology which are temperature dependent and independent voltage references. PWM controller is designed by using 3.3 volt supply voltage and the output frequency is 1MHz. From simulation results, the variation of output pulse width is less than form +0.86% to -0.38% in the temperature range $0^{\circ}C\;to\;70^{\circ}C$.
