18a) A differential amplifier has a gain of 100. A common input of SmV is applied
to both terminals, which result in an output voltage of 18mV. Determine
i) common mode gain ii) CMRR.
If the input signals are changed 10 50۷ and 100mV with 1۷ of noise on
each input. Find iii) the output signal iv) the noise on the output

b) For the op-amp circuit shown in the fig.2 find the output voltage equation.
