摘要： A digitally controlled oscillator is provided. The digitally controlled oscillator includes a pair of transistors cross-coupled to each other, a switched capacitor array coupled to the pair of transistors and a plurality of frequency tracking units coupled to the pair of transistors. The pair of transistors provides an output signal. The switched capacitor array tunes a frequency of the output signal. The frequency tracking units tune the frequency of the output signal to a target frequency. At least one of the frequency tracking units is capable of selectively providing a first capacitance and a second capacitance. A tuning resolution of the frequency tracking unit is determined by a difference between the first and second capacitances.

摘要： A tunable inductor includes a main wiring and at least one tuning module. The main wiring is arranged to encircle an inductor area of the tunable inductor. In addition, the tuning module is arranged to couple associated nodes of the main wiring. For example, each tuning module of the at least one tuning module includes a first switch positioned within the inductor area, and further includes at least one auxiliary wiring. When the first switch is turned on, the tuning module couples two nodes of the main wiring, where the at least one auxiliary wiring is arranged to couple the two nodes when the first switch is turned on. In particular, a patterned ground plane is arranged to decrease the energy loss of the tunable inductor, and more particularly, to prevent the tunable inductor from suffering energy loss. The patterned ground plane includes some conductive sections forming a W-like shape.

摘要： An over-voltage protection circuit structure for protecting a high power translation circuit is provided. The over-voltage protection circuit structure receives an alternating current input and comprises a relay circuit, a voltage detection module, and an energy supply circuit. The relay circuit relays the alternating current input to the high power translation circuit. The energy supply circuit provides power to the voltage detection module in response to the alternating current input. The voltage detection module detects a voltage value of the alternating current input continuously. When the voltage value is greater than or equal to a first reference value, the voltage detection module generates an over-voltage signal. The relay circuit opens to cease delivering the alternating current input into the high power circuit in response to the over-voltage signal, thus the purpose of protecting the high power circuit is achieved.
