In the case of the ideal op-amp, the DC voltage of the VIN(+) and VIN(-) terminals match exactly when the input voltage (Vi) is 0 V.
I'm looking for an operational amplifier for input offset voltage is few micro voltage (for example, 5 to 10 micro voltage)..We are considering using the sensor signal output with a voltage follower circuit or a gain of about 100 times amp circuit. Q1: Bas...

Input offset voltage Input offset voltage is the voltage that must be applied between the two input terminals of an op-amp to null the output. Typical value of 741 IC is 6mV dc. .ustudy.in Input offset voltage .ustudy.in Input offset current ...

However, continually overstressing the inputs can cause a change in parameters, such as bias current and offset voltage. Even though it may not necessarily destroy the op amp, over-voltage should therefore be avoided if at all possible. Protection for over-voltage usually consists of adding ...
On the input side it you could set up an op amp in a servo loop to match the unused input to the voltage of the offset input. Set the frequency response of the servo loop to 10 Hz or lower and it will not interfere with the AC signal. ...
www.ti.com Application Note DC Parameters: Input Offset Voltage (VOS) Abstract Richard Palmer and Katherine Li Abstract The input offset voltage (VOS) is a common DC parameter in operational amplifier (op amp) specifications. This report aims to familiarize the engineer with the basics and ...
at least a first body bias voltage for the first well, and not the second well, that varies in response to a first body bias control value; and a control circuit configured to selectively generate the first body bias control value in response to an input offset voltage of the op amp.Augu...
This resistor is connected to either side of the null pins, depending on the polarity of Vos, and serves to balance the voltages at the input terminals of an op amp. 2 Effect of Component Mismatches in the Input Offset Voltage Consider the simplified input-stage circuit of the operational ...
