hi i am designing a 10Gbps transimpedance amplifier. i know the that the output impedance when the circuit has a buffer should be 50 ohm. but the input is connected to photo-diode and there is no mention of input impedance and input matching of Tia in any paper or books about transimpedance amplifiers. and i asked several journal tia paper authors and no one answered yet .should input of high frequency TIA be matched and if it should be to what impedance ? and how much the matching should be ? (valid references would be helpful)
