Abstract/Summary

The posicast principle is a control method that aims to dampen oscillations of a lightly damped system. It is known for its ability to reduce the sensitivity issues present in classical Posicast controller. In this paper, a hybrid Posicast controller is integrated into a conventional circuitry of a 3V to 6v DC-DC Boost converter, and a full-custom lay-out is designed using the 0.35um CMOS library. The system is then simulated in both pre-layout and post-layout designs with simulation results having similar outputs. The behavior of the CMOS controller is verified having similar outputs. The behavior of the CMOS controller is verified by comparing it with the MATLAB model behavior.

Experimental results show that the hybrid Posicast controller was able to improve the steady-state response by improving its settling time to 1.8ms, and was able to eliminate the startup output overshoot of the Boost Converter.
