Abstract
An integrated circuit oscillator which includes a capacitor, a reference current source coupled to the capacitor used to charge the latter, and a trigger circuit coupled to the capacitor having an upper input threshold for changing from a first state to a second state and a lower input threshold for changing from the second to the first state. A discharge circuit is coupled to the trigger circuit and is operative to discharge the capacitor in response to the trigger circuit changing states and to cease the discharging on changing back to its original state.
