Question
2. An Op Amp integrator, as shown in Fig. L9.4 pg. 202 (SM), has a feedback capacitor of 10 nF and an input resistor of 100 k?. Initially the output is zero. A constant offset of 10.3 ?V is applied to the input. The time it takes for the output offset to increase by 1.47 V is ____ s.
3. An Op Amp differentiator, similar to that in Fig. L9.5 pg. 203 (SM), has a feedback resistor of 59 k? (instead of 100 k?) and an input capacitor of 10 nF (instead of 10 nF). A triangular-wave input signal of amplitude 2.0 Vp-p and frequency 1.0 kHz is applied to the input. The output signal is a square wave of peak-to-peak amplitude ____ V.
10Meg 1ook O1uF 411 Figure L9.4: IntegratorExplanation / Answer
Answer :- 2) The given integrator is called as integrator with DC gain control. The input-output equation is-
V0(t) = -(1/RC)*(integartion of Vin )
Taking magnitude only to find out the time value-
1.47 *100000*10*10-9 = 10.3*t (after doing integration)
=> t = 142.718 micro-second
