技術說明

本發明為一個應用電晶體線性操作特性改善之注入鎖定範圍的除三注入鎖定除頻器。注入鎖定除頻器中的雙推式電路結構能產生兩倍振盪頻率訊號，且注入電晶體將此訊號與注入訊號混波，得到接近振盪頻率的訊號。此訊號在一特定頻率範圍內能使振盪訊號被鎖定，該頻率範圍即為除頻器之注入鎖定範圍。線性混波的結果改善了非線性操作下諧波成分複雜的缺點，能夠注入鎖定的頻率成分能量較高，較容易使振盪訊號被鎖定因此能擴大注入鎖定範圍。 The present invention is a divide-by-three injection-locked frequency divider (ILFD) applying the linear operating characteristic of transistors to improve the locking range. The push-push structure of the ILFD generates a signal with twice the free-running frequency from the original free-running signal, and the injecting transistor mixes this with the input signal to generate a signal which the frequency is adjacent to the free-running. This signal can then result in injection locking within a specific frequency range, which is the locking range. Nonlinear mixing results in a complicated combination of harmonics while linear mixing avoids this flaw. Linear mixing facilitates injection locking and this fact in turn extends the locking range.
