Abstract
The aim of this thesis was to compare an integer and a fractional order controller. They were compared for better accuracy, stability and lower voltage variation when connected to a step down DC-DC converter. A PMOSFET and an NMOSFET were used as converter switches. As a control signal pulse-width modulation (PWM) was used. The central operating frequency of the converter is 100Hz, while the switching frequency used is 100KHz. Their implementation was done experimentally through the Custom IC Design Tool of Cadence® in the 0.18 um technology of TSMC.
