dc.description.abstractThe design and implementation of a CMOS analog integrated circuit that provides versatile sliding-mode control laws for high-frequency switching power converters is described. The controller circuit implements general-purpose linear-surface state control laws incorporating compensating dynamics. The analog controller integrated circuit considers current-mode circuit techniques, hence exhibiting good performance as far as operation speed, power consumption, suitability to poorly regulated power supplies and robustness in front of interferences are concerned. Compared to previous designs, the circuit allows the extension of switching frequency operating margin in more than one decade. The circuit allows modular connection, being composed of externally linearized transconductors based on current conveyors, current-mode amplifiers and filtering stages, and a transimpedance high-speed hysteretic comparator. Full-transistor-level post-layout simulations for a CMOS 0.8 µm technology and experimental results validate the high-speed functionality of the proposed sliding-mode controller ASIC implementation. The circuit may be used either as a standalone IC controller or as controller circuit that is technology-compatible with on-chip switching power converters and on-chip loads for future powered Systems on Chip.
