On the gm-Boosted Miller-Effect Minimized Inverter-Cascode Transimpedance Amplifier for Sensor Applications

This paper presents the small-signal operation of a $g_{\mathrm {m}}$ -boosted inverter-cascode transimpedance amplifier which has not been reported previously and whose comprehensive analysis is available in any article or text-book. A simplified sequential equivalent-circuit method employed eliminates need for complicated circuit techniques. The shows that gain gain-bandwidth transimpedance-amplifier enhanced by -boosting amplifier. due to increased output impedance TIA, and, reduced input-referred miller-effect capacitance through trade-off employing loop. To verify actual performance improvement achieved, simulation results as well measured experimental are also provided.
