Q. Explain about Differentiator?
Shown in Figure is a differentiator which is obtained by replacing R1 in the inverting amplifier of Figure by a capacitor C. Assuming ideal op-amp characteristics, one has i = iC and vo = - Ri = - RiC. But since iC (t) = Cdvin (t) /dt ,we get
vo (t) = - RC dvin (t) / dt
which corresponds to a differentiator with a gain of -RC. In practice, however, differentiators are normally avoided because of high-frequency noise (which is accentuated due to a transfer function that increases with frequency) and stability problems (which make them oscillate).
Design a logic circuit when to provide an output when any two or three of four switches are closed.
You have to look up the data sheets for the LM317 (Not LT317), LT1006. V1 is a standard 9 volt battery, and the resistors are “through hole”. Label the test points in, V+, gnd, and
Measurements made on the self-biased n-channel JFET shown in Figure are V GS =-1 V, I D = 4 mA; V GS =-0.5V, I D = 6.25 mA; and V DD = 15 V. (a) Determine V P and I DSS .
