Abstract :
Presently, there is a growing interest in synthesizing current controlled circuits because of their advantages. So the purpose of this article is to describe the functioning of current mode Schmitt trigger in both inverting and non-inverting mode with the help of MO-CCCDTA (multiple output current controlled current differencing transconductance amplifier). A temperature independent current mode Schmitt trigger can be constructed using MO-CCCDTA and the output of that can be controlled by the current. There is no parasitic losses because passive elements are not used.Thus impedance is low and power consumption will comparatively low.LT SPICE is used as a simulation tool.
