Abstract
Described herein are various principles for operating a transmitter circuit to reduce noise affecting a signal being generated and reducing jitter. In some embodiments, a circuit is operated in a way that switching occurs at or above a bit rate of transmission, such that at least one switch changes state at least for every bit. Operating the circuit in such a way leads to a switching rate that is above a resonant frequency of the circuit and prevents large oscillations and noise from being inserted into the signal and causing communication problems.
