Abstract :
It is shown that complementary property for voltage transfer functions can be applied to operational transconductance amplifier (OTA) circuits without ungrounding the OTA outputs. This property is valid for single and multiple OTA circuits and can be applied to obtain different functions from a given one. Also, this complementarity property can be applied to exchange the OTA output and ground, extending Fliege´s transformation which maintain invariant the characteristic polynomial.
