Fontana, Giorgio and Tonello, Alessandro (2002) Exact design solutions for photodiode transimpedance amplifiers based on FET input OP-AMPs. UNSPECIFIED. (Unpublished)
We calculate the transfer function of an optical receiver composed by a photodiode and a FET input operational amplifier as a current to voltage converter. According to the theory of low-pass filters, the receiver bandwidth and quality factor are here analytically evaluated, proposing design solutions and their related sensitivity to eventual parameter fluctuations. We exemplify the combined action of photodetection and filtering comparing the analytical expression with full numerical SPICE simulations.
