To calculate the dominant pole, calculate the open circuit time constants C_inR = 0·2 × 10^€“12× 20 × 10³= 4 × 10^€“9S

(a) An integrator is shown in Fig. 7.50. Use zero-value time constants to estimate the dominant pole and short-circuit time constants to estimate the nondominant pole for this circuit. Use R = 20 kΩ, C = 50 pF, C_in = 0.2 pF, a_υ = 1000, and R_o = 5 kΩ.

(b) Compare your answers with a SPICE simulation.
