Hi all, Does anyone know how do I connect an OTA if I want to use it as a voltage-controlled current source, meaning that it will ouput an AC current when i supplied an AC voltage? Any guide I can refer to? And how do I adjust the gain or transconductance, gm? For example, OPA860 with pinout E,C,B, Iq. http://www.ti.com/lit/ds/symlink/opa860.pdf Thanks!
