Answer the following question regarding amplifiers:

please do question 2 and 3

Q1 (a) (b) Considering an op-amp, define what is meant by input offset voltage (Vos) and explain what causes it. Figure Qla shows an integrating amplifier with zero input. Derive an expression for the output voltage, Vo, and explain the effect that Vos will have on its operation. R W Vos C Figure Qla A •V₂
