Abstract
A transimpedance amplifier is provided which includes a feedback path. The feedback path includes a feedback resistor and a voltage generator. The feedback resistor has a parasitic capacitance associated therewith. The feedback resistor also has a first node at a first voltage. The voltage generator can be capacitively coupled to the feedback resistor at a second node via the parasitic capacitance. The voltage generator is configured to generate a second voltage at the second node which is substantially equal to the first voltage. This prevents a current from flowing through the parasitic capacitance thereby reducing and/or eliminating the effect of the parasitic capacitance on the transimpedance amplifier.
