Abstract
In this paper, two design procedures for sigmoid function using exponential function have been proposed implementing division operation and feedback methodology. Hyperbolic tangent function has also been synthesized using the later. All the proposed circuits along with their building blocks have been implemented using current mode device Operational Transconductance Amplifier (OTA). Sensitivities of the circuit and process parameters on the output have been calculated. Performances of all synthesized circuits have been verified with SPICE simulation, establishing the effectiveness of the proposed methodology.
