A circuit with an ideal OPAMP is shown in the figure. A pulse VIN of 20 ms duration is applied to the input. The capacitors are initially uncharged.
The output voltage Vout of this circuit at t = 0+ (in integer) is ______ V.
    Correct answer is '-12'. Can you explain this answer?

    The given circuit is shown below,
    Above figure can be redrawn as
    From above circuit it is clear that,
    V− =VIN= + 5 V
    V+= 0 V
    Here, V ≠V+
    It means, voltage at both terminals of op-amp are unequal and fixed so virtual ground concept is not valid here and op-amp work as a comparator.
    Thus, V >V+
    So, Vout =−Vsat
    Vout =−12 V
    Hence, the output voltage Vout of this circuit at t = 0+ is −12 V.
