Abstract
In accordance with embodiments of the present disclosure, a system may include a buffer and a switch coupled between the buffer and a voltage supply such that the switch controls a varying voltage at a varying voltage node coupled to the buffer.
Claims16
A system, comprising:
- an impedance selector;
- a first switch coupled between the impedance selector and a voltage supply;
- and
- a second switch coupled between the impedance selector and the voltage supply, such that the first switch and the second switch control a varying voltage at a varying voltage node coupled to an output of the impedance selector.
