Design of nonlinear single OTA resistive circuits
Shuyong Liu · Journal of North China Electric Power University · 2003
The inherent saturation nonlinearity of the operational traasconductance amplifier (OTA) is adopted in circuits design. It possesses nonlinear driving point v-i characteristics based on the piece-wise linear technology and the paramount condition for positive linear 3-port resistor. These circuits consist of one OTA and several positive linear resistors. The canonical circuit and design algorithm are presented. Several examples are given and validated by experiment.
