Abstract
A relaxation oscillator circuit includes a comparator including a first input, a second input, a bias input, and an output. The first input is coupled to a charging node, and the second input is configured to receive a reference voltage. The relaxation oscillator circuit further includes a first bias circuit configured to provide a bias signal to the bias input of the first comparator when a first node voltage on the charging node exceeds a first reference.
