Realization of Grounded Active Inductor Circuit with Only MOSFETs
In this paper, a grounded MOS only active inductor circuit is presented. The grounded active inductor circuit has a minimum number of MOS transistors. As a result, this presented active inductor circuit provides small chip area and low power consumption as 315 μW. Also, the proposed circuit has tunability property and the active inductor can operate in a wide frequency range between 10 MHz to 500 MHz. To analyze the performance of the proposed grounded active inductor, a second-order notch filter structure is realized. The center frequency of the notch filter is selected as 200 MHz and the noise voltage value is calculated as 8.37 nV/√Hz for this frequency. The designed active inductor and filter structures are simulated by LTSPICE using 0.18 μm CMOS process parameters.
