This paper presents two grounded MOS only active inductor circuits. Both circuits have only two MOS transistors and two biasing currents. Thus, the proposed active inductors provide small chip area, tunability, low power consumption with 150μW and 90μW, respectively. To analyze their performance, a second-order band-pass filter and a third-order high-pass filter structures are presented with low noise as 7.5nV/Hz and 9.14nV/Hz, respectively. The designed active inductors and filters are simulated in 0.18μm CMOS process parameters using LTSPICE.
