| Abstract: | A new type of voltage regulator circuit is proposed. Pulse width modulate (PWM) method is used to adjust the voltage, and the circuit is formed by bipolar analog circuit combining with digital circuit of integrated injection logical. The circuit is verified by simulation in closed loop. On the basis of circuit simulations, the processing and layout design is discussed. |
