Abstract Normal requirements for differential and common-mode input impedance of amplifiers for biological signals are reviewed. It is shown that these are not sufficient for satisfactory performance of amplifiers in myoelectric control applications, where accidental opening of the input circuit through electrode movement must not make the system susceptible to external noise. The additional constraint imposed by this application is examined, and a circuit is presented illustrating its practical resolution.
