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).

PNP The other kind of BJT is the PNP with the letters "P" and "N" standing for the majority charge carriers inside the dissimilar regions of the transistor. Figure:
Voltage is referred as Potential difference among two points. Potential means its force. I think so.voltage defination is 100% correct.
