The primary difference lies in the nature of the output and the control mechanisms.
In most practical OTA ICs like the or LM13700 , the transconductance is directly proportional to the bias current: Op–Amp Circuits Manual. Including OTA Circuits
The fundamental relationship governing an OTA is defined by its transconductance, which relates the output current ( Ioutcap I sub o u t end-sub ) to the differential input voltage ( The primary difference lies in the nature of
