Abstract: A voltage-controlled oscillator includes an LC bank, a negative resistor circuit, a DC block, an AC block including a source resistor, and a first bias circuit controlled by a junction node of a first and second transistor, wherein the first bias circuit provides a first feedback voltage to a first control node, and maintains a voltage at the junction node of the first and second transistors, and a second bias circuit controlled by the junction node, wherein the second bias circuit provides a second feedback voltage to a second control node and maintains a voltage at the junction node.
