Op Amps: Voltage to Current Transducer f2

[@BMM66666]

Hi Pro, is this circuit like an operational transconductance amplifier?

Similar in some respects, but an OTA has a different design, and typically would be used in applications such as a VCA (voltage-controlled amplifier) or VCF (voltage-controlled filter). OTA designs like these usually wind up being modeled as voltage sources, not current sources. In case you haven't seen it, I do have a video on OTAs: kzbin.info/www/bejne/fJnOq5eJqbaijpo
