Abstract:
High-speed CMOS ring voltage controlled oscillators with low supply sensitivity have been disclosed. According to one embodiment, a CML ring oscillator comprises a CML negative impedance compensation circuit comprising two cross coupled transistors and a resistor connected to the two transistors for resistive biasing and a CML interpolating delay cell connected in parallel with the CML negative impedance compensation. An impedance change of the CML negative impedance compensation due to supply variation counteracts an impedance change of the CML interpolating delay cell.
