Abstract
An oscillator circuit includes an integrator, a comparator, an edge triggered flip-flop, and first and second capacitors. The edge triggered flip-flop has an input terminal coupled to an output terminal of the comparator and is configured to output first and second signals which are mutually exclusive, and to flip the signals when detecting a rising or falling edge output by the comparator such that: when the first signal is at a designated level, the first capacitor is charged and the second capacitor is discharged, and a terminal of the first capacitor is coupled to an input terminal of the integrator; and when the second signal is at a designated level, the second capacitor is charged and the first capacitor is discharged and a terminal of the second capacitor is coupled to the input terminal of the integrator.
