Question

a certain op-amp has bias currents of 45.3 μa and 44.2 μa. the input offset current is ua

Explanation:

Step1: Define offset current formula

The input offset current \(I_{OS}\) is the absolute difference between the two bias currents:
\(I_{OS} = |I_{B1} - I_{B2}|\)

Step2: Substitute given values

Let \(I_{B1} = 45.3\ \mu\text{A}\) and \(I_{B2} = 44.2\ \mu\text{A}\):
\(I_{OS} = |45.3 - 44.2|\ \mu\text{A}\)

Step3: Calculate the difference

\(I_{OS} = 1.1\ \mu\text{A}\)

Answer:
