ABSTRACT:
A high speed, low-power transresistance amplifier incorporating a threshold-biased, current-mode feedback inverter. Starvation transistors are connected between the inverter's power supply terminals and the supply. Capacitors are connected between the power supply and the nodes at which the starvation transistors are connected to the inverter to bypass the starvation transistors and decrease the AC impedance of the nodes, as seen by the inverter. A resistive network connected between the starvation transistors and a bias voltage supply decreases the effective DC impedance of the nodes.
