Abstract
A high-efficiency tracking power supply featuring a network of switched capacitors and an active noise shaping unit for reducing non-linearity and controlling the noise spectrum. Several variations of a non-inductive switched-capacitor tracking power-supply are presented, which are well-suited to integrated-circuit implementation and battery operation, and which provide an efficient power supply for the output stage over a wide range of voltages that can exceed the voltage limits of the main power source. The output of the tracking power-supply can be fed into an analog linear voltage regulator, or can be used as a Multi-Level Quantizer for generating the output directly. Some simple switching strategies are disclosed which offer power efficiencies in excess of 90%.
