Unformatted text preview: up as in integrator. The voltage across the capacitor is proportional to their charge q(t) , which grows as the time-integral of the input current, i(t) . Fig. 23-11: The dependent source model of an integrating op amp circuit. Fig. 23-12: The input voltage v in (t) to the integrating op amp. Fig. 23-13: The output voltage v out (t) of the integrating op amp. Fig. 23-14: An op amp set up as a signal averager. The output voltage v out (t) is proportional to the average of the input voltage. Lecture 23 figures 4 Fig. 23-15: The input voltage v in (t) to the averaging op amp. Fig. 23-16: The output voltage v out (t) of the averaging op amp. Fig. 23-17: An op amp circuit with a first-order network at the input. Fig. 23-18: The voltage output from the op amp circuit of Fig. 23-17. Fig. 23-19: The voltage input to the op amp circuit of Fig. 29-17. Fig. 23-20: The output voltage for the input of Fig. 23-19....
