Abstract

A complementary VHF CMOS active inductor is described. The proposed circuit employs 'p-type' and 'n-type' active inductor to obtain enlarged signal handling ability. Under the same inductance, Q value, and power consumption, the proposed circuit shows more than 12-㏈ improvement in dynamic range while maintaining high-frequency operation. Further enhancement is obtained by using a fully differential floating inductor structure. A 1-㎓ 4$\^$th/-order coupled-resonator filter is designed to demonstrate the potential of the proposed active inductor.
