摘要： A digital phase frequency detector includes a detection unit, a reset unit and a phase comparison unit. The detection unit detects edges of a reference signal and a feedback input signal to generate a reference edge signal and a feedback edge signal. The reset unit generates a reset signal resetting the detection unit based upon the reference edge signal and the feedback edge signal. The phase comparison unit generates first and second phase comparison signals based upon the reference edge signal and the feedback edge signal. The phase comparison unit includes a first flip-flop generating a first comparison signal based upon the reference edge signal and the feedback edge signal, a second flip-flop generating a second comparison signal based upon the reference edge signal and the feedback edge signal, and a latch block latching the first and second comparison signals to generate the first and second phase comparison signals.

摘要： A voltage controlled oscillator outputting a differential signal includes: an inductor connected to a first power supply supplying first voltage; first and second transistors for differential switching; first and second variable capacitors connected to the inductor in parallel; a third transistor of which a gate electrode is connected to a first node; and a fourth transistor of which a gate electrode is connected to a second node. When bias voltage is applied to the gate electrode of the first transistor to be turned on, negative resistance is generated by voltage applied to the first capacitor and the second capacitor through the first transistor. When voltage outputted through the first node is applied to the gate electrode of the third transistor to be turned on, the voltage is additionally applied to the first capacitor and the second capacitor by the third transistor to increase the negative resistance.
