    摘要: Circuits and methods for controlling a VCO output signal. A filtered version of an integral path input signal controls current flow through a proportional path. An exemplary embodiment generates an integral path input signal from a digital to analog converter. First integral path circuitry includes a first transistor device and a low pass filter which provides a filtered version of the integral path input signal to a first transistor device to control conduction through the device, providing a first VCO input signal for frequency adjustment of the output signal. Proportional path switching circuitry between a supply terminal and VCO input terminal includes a second transistor device which receives the first VCO input signals to control conduction between the supply terminal and the first VCO input terminal to provide a second signal for adjustment of the phase of the VCO output signal relative to the reference signal.

    摘要: System and circuitry controlling characteristics of periodic signals. In one embodiment adjustment circuitry modifies periodic signal characteristic. A phase detector generates analog input signals indicative of a phase difference between the periodic signal and a reference signal. Conversion circuitry translates the analog input signals into digital signals. Signal driving circuitry, comprising a current source, provides control signals to the signal driving circuitry based on the digital signals. First input circuitry provides a first adjustment signal to the adjustment circuitry. Second input circuitry provides a second adjustment signal to the adjustment circuitry in response to the control signal. The first adjustment signal is based on input of analog signals to a circuit element in the first input circuitry to control the first adjustment signal. The second input circuitry is responsive to the control signal to provide the second adjustment signal with the digital version of the input signals.

    摘要: A system and method providing power supply rejection. One embodiment provides for power supply rejection in PLL or DLL circuitry. First subcircuitry provides second subcircuitry a supply voltage which is a filtered version of power from an external source. The first subcircuitry includes a first field effect transistor and a first low pass filter coupled to receive a signal from the external power source during operation of the second subcircuitry. The filter is coupled to provide a filtered version of the power source signal to the gate of the first transistor, so that when a first source/drain region of the first transistor is connected to receive power from the external source and the gate of the first transistor receives the filtered version of the power source signal, the second source/drain region of the first transistor provides a first modified version of the power received from the external source.
