What are some recommendations for the bias circuit?

For our testing, we use a voltage divider bias circuit with a load resistor set at either 1 Megohm or set at a resistance equal to the dark resistance of the detector. The opamp can be nearly anything with a high input impedance. We recommend an FET input op amp which typically have an input resistance of approximately 10^12 ohms and work well. Please see our detector technical notes section for a diagram of a simple test bias circuit.
