Abstract
A stage for a voltage controlled oscillator includes a first p-channel transistor having a gate defining a control node, having a source adapted to be coupled to a supply voltage, and having a drain; a second p-channel transistor having a gate coupled to the control node, having a source coupled to the supply voltage, and having a drain; a first n-channel transistor having a gate defining a first input, having a drain coupled to the drain of the first p-channel transistor and defining a first node, and having a source; a second n-channel transistor having a gate defining a second input, having a drain coupled to the drain of the second p-channel transistor and defining a second node, and having a source; a current draw; first and second loads; a first source follower having an input coupled to the first node; and a second source follower.
