On the g<inf>m</inf>-Boosted Miller-Effect Minimized Inverter-Cascode Transimpedance Amplifier for Sensor Applications. IEEE Access. 9. (pp. 140525-140537).http://hdl.handle.net/10179/20392This paper presents the small-signal operation of a gm-boosted inverter-cascode transimpedance amplifier which has not been reported previously and whose comprehensive analysis is not available in any reported article or text-book. A simplified sequential equivalent-circuit method is employed which eliminates the need for complicated circuit analysis techniques. The analysis shows that the gain and the gain-bandwidth of the gm-boosted inverter-cascode transimpedance-amplifier is enhanced by the gain of the gm-boosting amplifier. This is due to the increased output impedance of the TIA, and, the reduced input-referred miller-effect capacitance through miller-effect trade-off employing the gm-boosting loop. To verify the actual performance improvement achieved, circuit simulation results as well as measured experimental results are also provided.140525-140537CC BY 4.0https://creativecommons.org/licenses/by/4.0/Analog CMOS circuitsgm-boostinginverter-cascode transimpedance amplifiersmall-signal analysissimplified inspection-based analysis techniqueJournal article10.1109/ACCESS.2021.31196422169-35362023-10-18Massey_Darkjournal-article
