Abstract

An integrated circuit includes a converter for converting a first DC voltage from a DC voltage source to an AC signal. The converter include an inductor and a transistor. The inductor and an intrinsic capacitance of the transistor provide an oscillating circuit without a need for a transformer. The integrated circuit also includes a rectifier for rectifying the AC signal to form a second DC voltage which has a sign opposite to the sign of the first DC voltage.
