Integral circuit with approximately ideal characteristics

If there is an error in the term with ", -" in the formula, you can increase the leakage voltage Vos or increase the resistor
R2 marked with ★ to compensate for J. The error caused by the cover can be reduced, or the error can be reduced by reducing the resistance of roar and increasing the capacity of c.     As shown in Figure ^, when an AC signal is input,. It can be seen from the frequency axis that . It is extremely critical to set the position in the circle. The frequency is low and fc, and the gain rises at 10 6dB/oct c20dH/dec). When = 0, the gain should be infinite (subject to the open-loop gain limit) o :j To obtain For incomplete integration characteristics, a feedback resistor Ri can be added ( connected with C). Assume 4=-Hall, / and l,, = 1/2 FR,. cl, so that the open-loop frequency characteristics of the OP amplifier with internal position compensation are the same as those of the integral circuit.     If there is an error in the term with ", -" in the formula, you can increase the leakage voltage Vos or increase the value marked with ★ Resistor R2 to compensate J.
