    摘要： A phase-locked loop circuit includes a phase and frequency detector receiving a reference signal and an output signal of the phase-locked loop circuit for generating a detected signal representing a frequency or phase difference therebetween. A digital charge pump coupled to the phase and frequency detector generates a charge control signal in response to the detected signal. A mixed mode loop filter coupled to the digital charge pump filters the charge control signal and generates an oscillation control signal. A voltage controlled oscillator is coupled to the mixed mode loop filter for generating the output signal of the phase-locked loop circuit by adjusting its oscillation frequency in response to the oscillation control signal. The mixed mode loop filter has both digital and analog characteristics in carrying out filtering the charge control signal, thereby reducing a layout area for the same to be implemented on a semiconductor substrate.

    摘要： An electronic device (100) using a cover mechanism (30) to cover its hole (14) of its housing (10) is described. The cover mechanism includes a cover (20) and a locking structure (11). The cover has a latching portion (23) and a locking portion (21), both of which include a resilient part. The locking structure is configured for associating with the locking portion and the latching portion. Thus, the cover is latched to the housing to cover the hole by deforming the resilient parts. After the cover is unlatched from the housing by a sudden pulling force, the locking portion still physically connects to the locking structure. After the cover is unlatched from the housing by a normal pulling force, the locking portion has no physically relationship with the locking structure.

    摘要： A variable attenuator assembly (1) includes a variable attenuating connector (VAC) (11), a coupling sleeve (12), and a second plug-type connector (13). The VAC includes a housing (20) and an attached double screw mechanism (110). The double screw mechanism is finely adjustable because it uses an adjusting knob (40) having an external thread (401) and an internal thread (402) with different screw pitches. The external thread engages with an internally threaded bore (303) of a connecting nut (30) attached to the housing. The internal thread engages with outer threading (602) on a ferrule holder (60) received in the adjusting knob. When the adjusting knob is rotated, the knob moves in one direction, and the ferrule holder is moved in the opposite direction, the total distance of ferrule holder movement relative to the housing being proportional to the difference between the screw pitches.
