摘要： An inductance-capacitance (LC) oscillator including a first varactor cell, a first transistor, a second transistor and a first pair of differential transformers is provided. The first varactor cell provides a first variable capacitance to adjust/tune the frequency of a first differential oscillation signal generated by the LC oscillator, and outputting the first differential oscillation signal. The first transistor is coupled between a core dc supply voltage and a first terminal of the first varactor cell. The second transistor is coupled between a ground potential and a second terminal of the first varactor cell. The first pair of differential transformers is connected in cascade with the first transistor and the second transistor between the core dc supply voltage and the ground potential, and is used for increasing the output-swing of the first differential oscillation signal, and making a current flowing through the first transistor to be reused by the second transistor.

摘要： An injection-locked frequency divider is provided and which includes an injection transistor, an oscillator, a current source and a transformer. The injection transistor is used to receive an injection signal. The oscillator is used to divide the injection signal to generate a divided frequency signal. The current source is coupled to the oscillator to provide a current to the oscillator. The transformer is coupled between the injection transistor and the oscillator to increase the equivalent transconductance of the injection transistor, and thus increasing the locking range of the injection-locked frequency divider.

The OSC is configured for dividing the frequency of the injection signal, so as to generate a first divided frequency signal, where there is an integral-multiple relation between the frequency of the first divided frequency signal and that of the injection signal. The buffer stage is configured for receiving and boosting the first divided frequency signal, and performing a push-push process on the first divided frequency signal, so as to output a second divided frequency signal, where there is a fractional-multiple relation between the frequency of the second divided frequency signal and that of the injection signal.

摘要： A video summarized method based on mining the story structure and semantic relations among concept entities has steps of processing a video to generate multiple important shots that are annotated with respective keywords: Performing a concept expansion process by using the keywords to create expansion trees for the annotated shots; rearranging the keywords of the expansion trees and classifying to calculate relations thereof; applying a graph entropy algorithm to determine significant shots and edges interconnected with the shots. Based on the determined result of the graph entropy algorithm, a structured relational graph is built to display the significant shots and edges thereof. Consequently, users can more rapidly browse the content of a video and comprehend if different shots are related.
