A sensor voltage vi from a sensor is amplified using the amplifier depicted below on the basis of the following specifications: R1 = 3.9 kW ±0.5%; R2 = 100 kW ±0.5%; |Voff| < 1.5 mV and |Ibias| < 100 nA. The sensor voltage appears to be vi = 0.2 V ± 0.2%,
Calculate vo and find the error in this voltage which is divided into an additive error (in mV) and a multiplicative error (in %).
Find the tolerance margins of vo.
