DIODES Sample Problems - Dr. Aydın ˙ I. Kars ¸ılayan 1. For the following circuits, sketch: • V o vs. V i • V o ( t ) for V i ( t ) = 2 sin(2 π 100 t ) Assume that the opamp is ideal, and show all your calculations. Simulate the circuits using D1N4002 diode, and provide all schematics and necessary plots to verify your results.
