Abstract

This paper presents a mix-signal, nonlinear weighted PID control DC-DC converter using TSMC 0.25 μm process and the input and output voltages are 12 V and 1 V. The maximum output power is 3 W. The digital control circuit is powered by the LDO when start-up. The output voltages 1 V and 2.5 V are produced by the series buck converter. The first buck stage provides 2.5 V output for powering the digital circuit only after start-up. The second buck stage provides output 1 V as the final output for the converter. The nonlinear weighted PID control improves 80% of the transient response time than the traditional PID control method.
