Abstract
In this paper, authors propose an adept design methodology of pseudo-logarithmic function as a network of operational transconductance amplifier(OTA), a current mode device. It demonstrates an inherent tunable and programmable property of OTA to improve the performance of the logarithmic function. The performance of the circuits have been verified with SPICE simulation. Those results show the improved performance over the existing methods.
