초록
In this study, we design the one-chip PWM IC for SMPS (Switching Mode Power Supply) application. We determine the IC spec. and simulated each block of PWM IC (Reference, Error amp., Comparator, Oscillator) with Smart Spice (SILVACO Circuit Simulation Tool). Reference circuits generate constant voltage(5V) in the various of power supply and temperature condition. Error amp. is designed with large DC gain (
