本文提出一种只使用两只晶体管和少量RC元件的低耗模拟电感。这种电感性能稳定,调整简便,只要改变某一R或C值即可达到要求,并可通过补偿使其Q值达到指定的数值。理论分析和实验结果一致。用此模拟电感制成的高通滤波器,性能良好,可以在工程中应用。 This paper presents a low-loss analog inductor that uses only two transistors and a small number of RC components. This inductor is stable, easy to adjust, as long as the change of a R or C value to meet the requirements, and can be compensated so that the Q value reaches the specified value. The theoretical analysis is consistent with the experimental results. The high-pass filter made with this analog inductor performs well and can be used in engineering applications.
