I want to design Transimpedance amplifier for photodiode.
I tried to simulate the reference configuration but it seems not to work combine between LT6200 and BF862, JFET work in negative gate-to-source voltage (the feedback return +2V).
I come to this design because i want to avoid large input capacitance. do any other suggestion, how can i use avaiable JFET in LTSpice combine with LT6200 ?
Thank everyone.
