Input bias current (or input offset voltage) may be measured using the test circuit of Figure 4. To measure IB, a large resistance, RS, is inserted in series with the input under test, creating an apparent additional offset voltage equal to IB×RS.

The op-amp datasheet usually specifies the input bias current as the average value of the input bias current IB+ at the non-inverting terminal and the input ... |
One of the golden rules of op amp analysis says this: no current flows into either input terminal. This concept is key for analyzing an amplifier's signal gain. |
In this article, we discuss two methods for testing input bias current. The method we choose depends on the magnitude of the bias current. We'll present the ... |
