Opвђ“amp Circuits Manual. Including Ota Circuits -

: A standard op-amp (e.g., 741) provides a voltage output with low output impedance, while an OTA (e.g., CA3080) provides a current output with high output impedance .

In most practical OTA ICs like the or LM13700 , the transconductance is directly proportional to the bias current: : A standard op-amp (e
