OTA – Operational Transconductance Amplifier

The OTA is a transconductance type device, which means that the input voltage controls an output current by means of the device transconductance, labeled gm. This makes the OTA a voltage-controlled current source (VCCS), which is in contrast to the conventional op-amp, which is a voltage-controlled voltage source (VCVS).
