Abstract
A relaxation oscillator reduces temperature sensitivity and phase noise at low offset frequency by periodically swapping a first current and a second current so that after the first current has been input to a first pair of circuits and the second current has been input to a second pair of circuits, the second current is input to the first pair of circuits and the first current is input to the second pair of circuits.
