Patent number: 7772895Abstract: A signal generating circuit includes a detecting circuit, a charge pump, a first level shifter, a filtering circuit, a second level shifter and a controllable oscillator. The detecting circuit outputs a detecting signal according to a reference signal and an oscillating signal. The charge pump outputs a first output signal by performing a charging or discharging operation according to the detecting signal. The first level shifter adjusts a voltage level of the first output signal to thereby output a second output signal. The filtering circuit generates a first filtered control signal according to the second output signal. The second level shifter adjusts a voltage level of the first filtered controlling signal to output a second filtered control signal. The controllable oscillator outputs the oscillating signal according to the second filtered control signal.Type: GrantFiled: September 2, 2008Date of Patent: August 10, 2010Assignee: ALI CorporationInventors: Kuo-Kai Lin, Hou-Kuan Sung

Patent number: 7719330Abstract: A phase locked loop device is provided. The phase locked loop device includes a phase/frequency detector, a charge pump, a low pass filter, a voltage-controlled oscillator, and a control unit. The phase/frequency detector generates a compared signal corresponding to a phase difference between a reference clock signal and a feedback clock signal. The charge pump coupled to the phase/frequency detector generates a pump current according to the compared signal. The low pass filter coupled to the charge pump generates an operating voltage corresponding to the pump current. The voltage-controlled oscillator coupled to the low pass filter generates an output clock signal in response to the operating voltage. The control unit coupled to the low pass filter and the voltage-controlled oscillator constrains the operating voltage to a predetermined voltage level when the frequency of the output clock signal is out of a predetermined frequency range.Type: GrantFiled: December 26, 2007Date of Patent: May 18, 2010Assignee: Ali CorporationInventors: Kuo-Kai Lin, Hou-Kuan Sung
