Abstract:
An oscillator circuit including a ring oscillator and a reference current source is provided. The ring oscillator includes an odd number of inverter stages. Each inverter stage includes a first transistor having a first reference threshold that varies over temperature. The reference current source is configured to generate a plurality of currents, where a respective current is applied directly to the drain of a respective first transistor of a respective inverter stage. The reference current source includes a reference transistor that has a second reference threshold that varies over temperature; a resistor coupled between a gate and a source of the reference transistor; a second transistor having a source coupled to the gate of the reference transistor for generating a reference current that flows through the resistor to regulate a voltage of the resistor to the second threshold voltage; and a current mirror configured to generate the plurality of currents.

Claim (Index 19):
The integrated circuit according to  claim 18 , wherein the plurality of currents are respectively provided to the plurality of drains of the respective plurality of first transistors of the plurality of inverter stages, wherein the resistor has first and second terminals and the reference transistor has a drain configured to receive a bias current, a source coupled to the first terminal of the resistor and configured to receive the reference voltage and a gate coupled to the second terminal of the resistor.
