The integrator (LM318) circuit diagram with expanded timing range

The integrator can easily work with a very short and very long time constant. The integration time constant is ( R2/R1) RC , if the precision of resistors R1 , R2 is ± 0.1 % , you can get a very good linearity . The advantages of this circuit are: it is easy to adjust its initial state because the capacitor is grounded with one end. If the switch is grounded at one end, the output is zero when switch is closed, the initial state is zero ; If one end of switch is connected to voltage V1, the initial state is V1. The integration period of the circuit can be as short as 1ns or as long as 1000s. The bandwidth of the integrator depends on the characteristics of the op amp. The integrator composed of LM318 and CA3100 op amps is suitable for high frequency signal points.
