Hi,

I am designing a preamp for photodiode. I ac couple the signal from diode and feed into transimpedance amp. but when I provide a DC leakage current path through a high valued resistor to ground,my signals are lost.
Why does providing a DC leakage current path to ground does not work for higher values of leakage current?
