(a) Use Eq. (2.5) to obtain the amplifier open-loop gain A required to realize a specified closed-loop gain within a specified gain error ,(b) Design an inverting amplifer for a nominal closed-loop gain of 100, an input resistance of 2 k, and a gain error of 10%. Specify R1, R2, and the minimum A required.

Module 2D : XOR/ XNOR gates AN XOR gate is a 2 input gate whose output is “1” if exactly one of its inputs is 1 or if its inputs are different. The Truth table is similar to an OR function except for the 1 – 1 combination. An XNOR gate is the inverse of the XOR gate. The dual and complement of an XOR gate both are the same. This is an interesting property. An XNOR gate is also referred to as an XAND gate. This function is non reducible. We use a symbol which is called “ring – sum”. This is basically a way of saying the inversion of X anded with Y and or’ed with X anded with the inverse of Y. XOR properties o X X = X•X + X•X = 0 + 0 = 0 o X X = X•X + X•X = 0 + 0 = 0 o X 1 = X •1 + X•0 = X o X 1 = X•1 + X•
