Popis: To solve the existing problems such as lower quality factor and inductance value in common active inductor, a novel cascode-grounded active inductor circuit topology was proposed. The R f is added and the RC feedback cascode positive feedback is formed used to substantially improve equivalent inductance and quality-factor. This novel active inductor was implemented by using a TSMC 0.35-μm 3P4M SiGe BiCMOS technology, which demonstrates a maximum quality factor of 2563 with an inductance of 3.165nH at 4.3GHz.
