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 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 johnny cash style clothing shows that the gain and the gain-bandwidth of the $g_{mathrm {m}}$ -boosted inverter-cascode transimpedance-amplifier is enhanced by the gain of the $g_{mathrm {m}}$ -boosting amplifier.This is due to the increased output impedance of the TIA, and, the reduced input-referred miller-effect capacitance rosy teacup dogwood through miller-effect trade-off employing the $g_{mathrm {m}}$ -boosting loop.

To verify the actual performance improvement achieved, circuit simulation results as well as measured experimental results are also provided.
