研究目的
To optimize the bandwidth of the injection-locked transformer using inductor coupling technique for high-frequency broadband injection-locked divide-by-two divider.
研究成果
The proposed high-frequency broadband injection-locked divide-by-two divider increases the frequency and widens the locking range without increasing the chip area and power consumption. It achieves a frequency division of 71.8-87.9GHz with a frequency division ratio of 18.3%, making it well suited for the application of the first stage divider design in millimeter-wave phase-locked loops.
研究不足
The paper does not explicitly mention the limitations of the research.
1：Experimental Design and Method Selection:
