Two case examples of high-speed CMOS microelectronic implementations of high-performance controllers for switching power converters are presented. The design and implementation of a current-programmed controller and a general-purpose feedforward one-cycle controller are described. The integrated circuit controllers attain high-performance by means of using current-mode analog signal processing, hence allowing high switching frequencies that extend the operation margin compared to previous designs. Global layout-extracted transistor-level simulation results for 0.8 μm and 0.35 μm standard CMOS technologies confirm both the correct operation of the circuits in terms of bandwidth as well as their functionality for the control of switching power converters. The circuits may be used either as standalone IC controllers or as controller circuits that are technology-compatible with on-chip switching power converters and on-chip loads for future powered systems-on-chip.
