Abstract:
1. A capacitive energy transfer converter including: (a) at least one capacitive charge pump controlled by at least one clock input signal, for providing an output voltage supply based upon a coupled source voltage; (b) a clock circuit for generating a clock signal, the clock circuit including an active driver circuit configured to both source current to and sink current from the clock circuit and current limiter circuitry configured to limit the source current and the sink current so as to cause a voltage waveform of the clock signal to be substantially sine-like; and (c) one or more capacitive coupling networks configured to capacitively couple the clock signal to the at least one capacitive charge pump as one such at least one clock input signal, wherein the capacitive coupling necessitates that the clock signal be substantially sine-like.
