    摘要: Various embodiments of the invention provide a varactor structure that, depends on configurations, can provide a C-V characteristic based on one or a combination of a reverse bias junction capacitor, a channel capacitor, and an oxide capacitor. The junction capacitor is formed by reverse biasing the P+ source region and the N-well. The channel capacitance is formed between the P+ source region and the N+ drain region, and the oxide capacitor is formed in the gate oxide area. Depending on biasing one or a combination of the gate voltage VG, the source voltage VS, and the drain voltage VD, embodiments can utilize one or a combination of the above capacitors. Other embodiments using the varactors in a Voltage-Controlled Oscillator (VCO) are also disclosed.
