Patent ID: 7642872

Claim:
An oscillator circuit for use in integrated circuits, the oscillator circuit comprising: a current mirror having at least a first current mirror branch and a second current mirror branch, the current mirror comprising a first NMOS transistor and a second NMOS transistor, a gate of each of the first NMOS transistor and the second NMOS transistor being coupled to one another, the first NMOS transistor is coupled to act as a forward-biased diode; a current source coupled to the first current mirror branch; a capacitive element coupled coupled in series with the first NMOS transistor; and a resistive element coupled to the second current mirror branch; a plurality of inverting elements coupled in series with one another; a transconducting element coupled to an output of the plurality of inverting elements, the transconducting element configured to discharge the capacitive element; and a latching element, the latching element coupled to latch to an output signal of the plurality of inverting elements.
