技術摘要 / Our Technology: |
一種相位差信號驅動式直流電壓產生裝置,其可應用於例如整合至相位鎖定迴路(phase-locked loop, PLL)或延遲鎖定迴路(delay-locked loop, DLL)之電路系統,用以提供一相位差信號驅動之直流電壓產生功能;且其電路架構包含一電荷泵單元、一迴路濾波器單元、一電壓倍增器單元、以及一激脈濾波器單元;而其特點則在於可利用該電壓倍增器單元來倍增該電荷泵單元的輸出電壓,以藉此來提供一更廣範圍的控制電壓來增強PLL和DLL電路系統的輸出特性。
A differential signal driven direct-current voltage generating device is proposed, which is designed for use with a PLL (phase-locked loop) circuit or a DLL (delay-locked loop) circuit system for generating an output of a direct-current (DC) voltage in response to a pair of differential signals, such as phase-difference signals; and which is characterized by the utilization of a capacitor-switched voltage doubler for doubling the output voltage of a charge pump so that the doubled voltage can be used as a control voltage for a PLL-VCO (voltage-controlled oscillation) or a DLL-VCDL (voltage-controlled delay line) circuit for generation of an output oscillating signal with a wider frequency range.
