Did you know?
WebOct 15, 2024 · The effect of scaling the p-channel transistors on the offset voltage of the op-amp is to reduce the offset voltage from 7.2mV to 3.7mV. Doing some math, the p-channel offset contribution is ~6.4mV and the n-channel contribution is ~3.3mV. Verifying the offset voltage, the initial offset voltage is (6.4 2) + (3.3 2) = 7.2mV. http://www.ecircuitcenter.com/Circuits/op_voff/op_voff.htm
WebMar 4, 2016 · Its possible with almost any amp. Why does this happen, it really depends on the op amp and how it was designed and manufactured. This is a histogram of the offset voltage for a different amplifier OPA1622, but most of them are similar. The histogram follows a normal distribution and it would be possible in some circuits to have the total ... WebMar 21, 2010 · Offset voltage. @jins. While the op-amp output should be 0 V when the input is 0 V, in actual operation there is some offset voltage at the output. For example, if one connected 0 V to both op-amp inputs and then measured 26 mV (dc) at the output, this would represent 26 mV of unwanted voltage generated by the circuit and not by the …
