Operational transconductance amplifier Usage on es. From Wikimedia Transconcuctancia, the free media repository. One of its principal uses is in implementing electronically controlled applications such as variable frequency oscillators and filters and variable gain amplifier stages which are more difficult to implement with standard op-amps.
