Can someone show neat writing and answer all. my exam is soon

04 (a) List the characte amecteriteristics of an ideal opamp and explain the meaning of each of a real opamp differ from the ideal opamp you described in part (a) these characteristics. (b) How does 121 (c) Figure Q4 shows an opamp circuit with negative feedback. Calculate the voltage across, Vout, and the current through each resistor if Vin is 2V. You can assume that the power supply is adequate to supply Vout without clipping 15) Vout ov 400n 2000 Figure Q4 Sketch two circuits, based around the one shown in Figure Q4, that could function as (i) a 3 bit DAC and (ii) a 6 bit DAC. You should indicate where the digital signals enter the circuit (d) whether the output of the DAC mirrors the 'significance' of the bits of the input signal? (e Which components in the circuits you have drawn in (d) above control
