- The output voltage of this circuit is given by;

- When we integrate a constant, we get a straight line. In other words, when input voltage to an integrator is constant, the output is a linear ramp. Therefore, the integration of the square wave results in the triangular wave as shown in Fig. 9.13 (ii). Since the input to the integrator is applied to the inverting input, the output of the circuit will be 180º out of phase with the input. Thus, when the input goes positive, the output will be a negative ramp. When the input is negative, the output will be a positive ramp. Fig. 9.13 (ii) shows this relationship.
