Q. Explain basic working of Integrators?
Figure shows a noninverting integrator, which can be seen to be a negative impedance converter added with a resistor and a capacitor. Noting that vo = 2v1 and i3 = v1/R, the total capacitor current is
which shows that the circuit functions as an integrator.
Replacing R2 in the inverting amplifier of Figure by a capacitance C results in the somewhat simpler integrator circuit shown in Figure, known as an inverting integrator, or Miller integrator. With ideal op-amp techniques, iC = iin = vin/R. The voltage across C is just vo, so that
which illustrates that the network behaves as an integrator with sign inversion.
Q. Obtain the Thévenin and Norton equivalent circuits for the portion of the circuit to the left of terminals a-b in Figure, and find the current in the 200- resistance.
Q. Consider a BJT switch connected to the next stage, as shown in Figure, in which iout is likely to be negative when v out is high. Assume V CC = 5 V, R C = 1k, and the high r
