Abstract: A frame-based phase-locked display controller used in a display system and method thereof are described. The frame-based phase-locked display controller for displaying a plurality of image frames in a video signal comprises a frame-based phase-locked loop and a synchronization signal generator. The frame-based phase-locked loop receives an oscillating signal and an input vertical synchronous signal to generate an output clock signal by phase-lock loop based on the frames. The synchronization signal generator, coupled to the frame-based phase-locked loop, receives the output clock signal to generate an output horizontal synchronous signal, an output vertical synchronous signal and an output display enable (DE) signal. The frame-based phase-locked loop comprises a first PLL, a frequency synthesizer, a second PLL, a fast phase detector, a phase frequency detector and an active pixel region generator.

Abstract: A switched-capacitor charge pump device is proposed, which is designed for integration to a circuit system, such as a PLL (phase-locked loop) circuit system, for generation of an output direct-current (DC) voltage with a wide amplitude range; and which is characterized by the utilization of two switched-capacitor circuit units in addition to the output capacitor circuit and the utilization of an output voltage comparing circuit (such as a Schmitt trigger) for comparing the end-result output DC voltage against a half-amplitude drive voltage such that when the switched-capacitor circuit units are subjected to a charging-discharging action for voltage pump-up or pump down operations, the switched-capacitor circuit units are switched between a full-amplitude drive voltage and a half-amplitude drive voltage. This feature allows the invention to provide an output DC voltage with a wider amplitude range than prior art.

Abstract: A unilateral feedback power amplifier utilizes new feedback techniques and devices to make the amplified high-frequency signal unilateral, let the output power, power gain and impedance matching simultaneously accomplish the optimal values, and enhance the stability of the system. In this feedback amplifier, a generalized multi-port feedback circuit is in shunt with the input terminal and the output terminal of the power transistor. This generalized multi-port feedback circuit receives an amplified high-frequency signal and eliminates the reverse admittance of the amplified high-frequency signal to let the admittance value of the output amplified high-frequency signal approach zero so as to be unilateral. Moreover, the generalized multi-port feedback power amplifier differs from the conventional power amplifier of cascaded architecture in that the ground terminal of the power transistor is directly connected to the system ground.
