1.     For a current to voltage converter incorporating a photodiode and opamp, the input resistance of the opamp should be ____. a) 0 b) decrease c) large d)    

         equal to the feedback resistance.

2.      For an APD, increasing reverse bias will _____ the gain M. a) increase b) not effective c) not effect d) need more information

Solution

1. For a current to voltage converter incorporating a photodiode and opamp, the input resistance of the opamp should be very large

2.  For an APD, increasing reverse bias will increase the gain M
