Abstract:
An oscillator that includes an energy storage system configured to store energy, a ramp circuit configured to generate an oscillating ramp signal having a slope that is a function of the amount of energy stored in the energy storage system, a charge circuit configured to controllably deliver energy into or remove energy from the energy storage system, a comparator circuit configured to compare the oscillating ramp signal with a reference signal; and/or a charge control circuit configured to cause the charge circuit to deliver energy into or remove energy from the energy storage system based on the comparison by the comparator circuit.
