Patent ID: 7271673

Claim:
A device comprising: a voltage controlled oscillator (VCO) having an inductive-capacitive (LC) tank, the VCO capable of activating and deactivating respective capacitor pairs of the LC tank with respective single switching transistors; wherein the VCO includes at least one VCO coarse tuning bank bit for a course tuning bank, the VCO coarse tuning bank bit comprising: a pair of capacitors including a first capacitor and a second capacitor; the first capacitor coupled to a first node, and the second capacitor coupled to a second node; a pair of bias transistors including a first bias transistor and a second bias transistor; the first bias transistor coupled between the first node and a third node, the second bias transistor coupled between the second node and the third node; a switching transistor coupled between the first node and the second node, the switching transistor including a gate terminal that receives a coarse tuning bank bit input signal; and an inverter that receives the coarse tuning bank bit input signal and produces an inverse coarse tuning bank bit input signal, the inverter to provide the inverse coarse tuning bank bit input signal to the third node.
