技術說明

一種雙注入鎖定式除頻電路，其可應用於整合至一高頻電路系統，用來對高頻之電子信號提供一除頻功能。此雙注入鎖定式除頻電路的特點在於採用一雙注入式之電路架構來將輸入信號分流成2個注入信號，包括一第一注入信號和和一第二注入信號；其中該第一注入信號係透過一直接注入方式及以電壓形式來注入至內部之振盪電路，而第二注入信號則係以電流形式進而利用一共振電路模組來注入至內部之振盪電路。此特點可提供更為寬大的頻率鎖定範圍及更低之耗電量。 A dual injection locked frequency dividing circuit is proposed, which is designed for integration to a gigahertz signal processing circuit system for providing a frequency dividing function to gigahertz signals. The proposed circuit architecture is characterized by the provision of a dual injection circuit on the input end for dividing the input signal into two parts for use as two injection signals, wherein the first injection signal is rendered in the form of a voltage signal and injected through a direct injection manner to the internal oscillation circuitry, while the second injection signal is rendered in the form of an electrical current and injected through a resonant circuit to the internal oscillation circuitry. This feature allow the proposed frequency dividing circuit to have broad frequency locking range and low power consumption.
