  • Abstract
    A low current front-end transimpedance amplifier (TIA) circuit for a high-speed light emitting diode (LED) and photodetector (PD) pair is presented. It mitigates PD capacitance effects by using a low input impedance buffer between the PD and the amplifier´s input stage. Our simulation results show that a bandwidth in excess of 100 MHz can be reached for PD currents below 100 nA in amplitude. An actual circuit was built to confirm the projected capabilities of the system.
