Phase locked loop apparatus with selectable capacitance device |
摘要 |
A phase locked loop apparatus includes an oscillator, a variable capacitance device, a selectable capacitance device, and a capacitance controller that is configured to provide a control signal to the selectable capacitance device. The selectable capacitance device is connected to the oscillator and is responsive to the control signal such that the selectable capacitance device has a first capacitance at a first control signal value and a second capacitance at a second control signal value. The capacitance controller only selects either the first capacitance or the second capacitance by providing a control signal that has the first control signal value to select the first capacitance and having the second control signal value to select the second capacitance. |
