Abstract
Embodiments of a potential converter circuit include a converter for converting a bipolar input signal to a unipolar output signal that only consumes current at a change of potential of the input signal.
Claims23
A potential converter circuit for converting a bipolar input signal to a unipolar output signal, the circuit comprising:
- a first switch coupled between an input and an output and comprising a first switching capacitance;
- and
- a second switch coupled between the output and a reference potential and comprising a second switching capacitance,
- wherein the first switch and the second switch are configured for charging and discharging the switching capacitances of the switches only at a change of potential of the input signal.
