i) The drift parameter of an operational amplifier used in a non-inverting amplifier is given below. Input offset voltage variation= +10 pV/C Input offset current variation= +0.7 nAC Assuming R = 2MQ and R = 300KN and output V 0 V at 25 C, find the output voltage al 60 C due to offset voltage variation and due to offset current variation.(5 Marks) ii) In the inverting AC amplifier circuit shown in Fig. below, V-1.5 V, C =0.01 uF, R=20O KO, and Re220 KO Calculate the lower 3dB frequency and the approximate closed-loop voltage gain in the mid-band range of frequencies.(5 Marks) Ry C.
