7042253	Self-calibrating, fast-locking frequency synthesizer A frequency synthesizer for dual-band high frequency RF application. The frequency synthesizer first uses a frequency-locked loop circuit (“FLL”) to achieve self-calibration and frequency-locking, and then uses a phase-locked loop circuit (“PLL”) to achieve ...	05/09/2006
6304144	Differential amplification circuit DC components are removed by a first and a second capacitor from a normal signal and its inverted signal from a first and a second input terminal, and the signals are input to a DC level generating circuit. The DC level generating circuit newly adds a DC ...	10/16/2001
4471286	Closed-loop frequency regulated generator apparatus In a motor-generator set, the frequency of the AC generator outputted voltage is automatically adjusted by field winding regulation of the DC motor, through a closed loop in which a dual-slope converter is charged during a clock-defined time interval in a...	09/11/1984
