Abstract
An integrated oscillator has an R-S flipflop; a first and second capacitor; a current source transistor; first and second current-steering transistors, each having a source coupled to the current source transistor, with drains coupled to the first and second capacitor respectively. The first current-steering transistor has gate coupled to a first output of the R-S flipflop, and the second current-steering transistor has gate coupled to a second output of the R-S flipflop. The oscillator has a first sense inverter having input from the first capacitor and powered by a feedback circuit adapted to sense voltages on the first and second capacitor; and a second sense inverter having input from the second capacitor and powered by the feedback circuit. The R-S flipflop has a first input coupled to an output of the first sense inverter and a second input coupled to an output of the second sense inverter.
