Abstract
An RC oscillator circuit is disclosed. The RC oscillator circuit includes a current generator configured to generate a charge current. The RC oscillator circuit also includes an integrator having an input and an output, the input being connected to the current generator. The RC oscillator circuit also includes a comparator having a first input, a second input, and an output, the first input being connected to the output of the integrator and the second input being configured to supply a reference threshold. The RC oscillator circuit also includes a clock pulse generator connected to the output of the comparator and a reference generator configured to generate the reference threshold based on a supply voltage of the RC oscillator circuit.
