FINDING THE TRANSIENT RESPONSE OF AN INTEGRATING CIRCUIT
The input signal v_{in} = sin(120πt + 90°) is to be integrated and then fed to a load resistance R_{L} = 1 GΩ. This is shown in Figure 13.24(a). Use PSpice to plot the transient response of the input and output voltages for a duration of 0 to 33.33 msec in steps of 10 μsec.
The integration is accomplished by the RC circuit of Figure 13.24(b). The input frequency is f = 60 Hz.
The PSpice schematic is shown in Figure 13.25(a) with a capacitor integrator. Figure 13.25(b) shows an implementation with an ABM integrator.
The listing of the circuit file is as follows:
Example 13.6 Integrating circuit
| SOURCE VIN 1 0 SIN (0 1V 60HZ 0 0 90DEG) CIRCUIT .PARAM FREQ = 60HZ ; Input frequency in hertz .PARAM TWO–PI = 6.2832 ANALYSIS .TRAN 10US 33.33MS UIC ; Use initial condition in transient analysis .END |
The plot of the transient response for the input and output voltages are shown in Figure 13.26. The output is a sine wave in response to a cosine signal.
