Original Abstract Submitted
Methods, systems, and computer products are presented herein for generating a clock signal using an on-chip ultra-low power (ULP) RC oscillator. An on-chip ultra-low power (ULP) RC oscillator comprises a first comparator, a second comparator, and a flip flop. The first comparator comprises a first input electrically coupled to a first bias voltage generation circuit and a second input electrically coupled to a first capacitor circuit. Each of the first bias voltage and the second bias voltage directly varies with a thermal voltage. A flip-flop is electrically coupled to the first comparator and the second comparator. The flip-flop is configured to generate a clock signal based on the first and the second comparator output signals.
