Abstract

This work introduces an active feedback structure into the Inverter Cascode Trans-Impedance amplifier design, allowing the enhanced circuit to achieve a reasonable 32 and 84 times improvement in bandwidth and power consumption respectively over the traditional circuit of Inverter Cascode Trans-Impedance amplifier utilizing resistor as feedback mechanism. The gain of the proposed enhancement circuit was determined to be 53.2 dB, with 9.2 GHz bandwidth and 3.2 mW of power consumption, hence the proposed design is appropriate for broad bandwidth applications designed to operate with low supply voltage.
