Yayın CMOS high-performance UWB active inductor circuit(Institute of Electrical and Electronics Engineers Inc, 2016) Momen, Hadi Ghasemzadeh; Yazgı, Metin; Köprü, Ramazan; Saatlo, Ali NaderiIn order to maximize efficiency of the designed gyrator-based active inductor, advanced circuit techniques are used. Loss and noise are most important features of the AIs, where they should be low enough to have high-performance device. The gyrator-C topology is used to design a new low-loss and low-noise active inductor. The gyrator-C topology is potentially high-Q and all transistors are utilized in common-source configuration to have high impedance in input-output nodes. All transistors are free of body effect. The p-type differential pair input transistors and the feed forward path are employed to decrease noise of the proposed circuit. Additionally, inductance value and quality factor are adjusted by variation bias current which gives to the device tunable capability. HSPICE simulation results are presented to verify the performance of the circuit, where the 180 nm CMOS process and 1.8 V power supply are used. The noise voltage and power dissipation are less than 2.8 nV/ ? Hz and 1.3 mW, respectively.Yayın A new high performance CMOS active inductor(IEEE, 2016) Momen, Hadi Ghasemzadeh; Yazgı, Metin; Köprü, Ramazan; Saatlo, Ali NaderiA new high-performance active inductor with ability to tune its self-resonance frequency and quality factor without affecting each other is presented in this letter. Using the input transistor of active inductor in cascoding configuration gives this property to designed circuit. Furthermore, the input transistor topology make the device robust in terms of its performance over variation in process and temperature. On the other hand, RC feedback is used to cancel the parasitic components in input node of the active device, which results to improve circuit performance. Schematic and post-layout simulation results shows the theory validity of the design. Monte Carlo and temperature analysis is done to show structure robustness in PVT variation. Inductive behavior frequency range of suggested structure is 0.3-11.4 GHz. Maximum quality factor is obtained as high as 3.7k at 6.3 GHz. Total power consumption is as low as 1mW with 1.8 V power supply.
