Voltage controlled oscillator |
| abstract |
A voltage controlled oscillator (VCO) conducts current on two paths through parallel inductors and parallel cross-coupled metal-oxide-semiconductor transistors. A pair of varactors are connected in series on a third path extending from a node between one inductor and one transistor to a node between the other inductor and the other transistor. The oscillation frequency is controlled by a voltage applied to a node between the two varactors on the third path. Each varactor is structured as a metal-oxide-semiconductor transistor with interconnected source and drain electrodes, a gate electrode, a body region below the gate electrode, and a body terminal region extending beyond the gate electrode. An adjustment voltage applied to the body terminal region shifts the voltage-capacitance curve of the varactor and the voltage-frequency curve of the VCO without changing the shapes of these curves, providing a simple way to adjust the VCO to meet application requirements. |
