Hello, I wanted to know which kind of trans-impedance amplifier to be used to read an input current in the range between nano to pico Amps from a silicon carbide photodetector. can anyone kindly suggest few IC's. Thanks in advance.

What is your criteria for "best" amplifier?
Gain, bandwidth, low noise, bias current, input capacitance, power supply, power consumption, foot print, price?

I have used AD8067 in the past with good results.
