Patent ID: 7889016

Claim:
An integrated oscillator, comprising: a first compensated inverter having input and output terminals respectively connected to first and second nodes, the first compensated inverter including a first plain inverter and a second plain inverter coupled in parallel to each other, the first plain inverter having a channel length that is shorter than a channel length of the second plain inverter; a second compensated inverter having input and output terminals respectively connected to said second node and to a third node, the second compensated inverter including a third plain inverter and a fourth plain inverter coupled in parallel to each other, the third plain inverter having a channel length that is shorter than a channel length of the fourth plain inverter; a resistor having a resistance value and comprising first and second terminals connected respectively to said first and second nodes; and a capacitor comprising first and second terminals connected respectively to said first and third nodes, and having a capacitance value, the inverters, resistor, and capacitor being configured to deliver a clock signal at the third node at an oscillation frequency.
