20120161886 | VOLTAGE CONTROLLED OSCILLATOR - A voltage controlled oscillator including a control signal adjuster and ring-connected delay cells is disclosed. The control signal adjuster receives a first control signal to generate a second control signal boosted from the first control signal when the first control signal is lower than a transistor threshold voltage. The ring-connected delay cells are controlled by the first and second control signals both to generate an oscillation signal. Each of the delay cells has a first set of current generation transistors and a second set of current generation transistors. Each transistor of the first set of current generation transistors has a control terminal receiving the first control signal while each transistor of the second set of current generation transistors has a control terminal receiving the second control signal. The first and second sets of current generation transistors collectively output an oscillation signal with unchanged frequency of associated input signal. | 06-28-2012 |
