Question

A standard inverting op-amp circuit has an R1 of 10 kΩ and an Rf of 220 kΩ. If the offset current is 100 nA the output offset voltage due to this current is ________.

Answer 1

The value is
`V_(os) = 0.001 \ V`

Step-by-step explanation:

From the question we are told that

The circuit resistance is
`R_1 = 10 \ k \Omega`

The feedback resistance is
`R_f = 220 \ k \Omega`

The offset current is
`I_(os ) = 100 \ nA = 100 * 1)^(-9) \ A`

Generally the offset voltage is mathematically reparented as

`V_(os) = R_f * I_(os)`

=>
`V_(os) = 10 *10^(3)* 100 *10^(-9)`

=>
`V_(os) = 0.001 \ V`
