    The gain of the OTA is a function of a programming current, \(I_{abc}\). Since \(I_{abc}\) may be derived from other electronic signals, complex dynamic gains are possible. Further, because the OTA tends to behave as an ideal current source (i.e., it exhibits a high output impedance), a constant voltage output is best rendered through the use of a following current-to-voltage transducer. Finally, the OTA can only tolerate fairly small input signals, so some form of input attenuation is normally used.
