Phase compensation of the three op amp instrumentation amplifier
The frequency stability of the popular 3 op-amp instrumentation amplifier is discussed. It is shown that the two input stage amplifiers of the conventional circuit should be compensated for unity gain. A simple modification to the circuit that allows the use of uncom-pensated amplifiers is demonstra...
