Abstract :
A new current-mode Schmitt trigger based on MO-CTTA (Multiple output current through transconductance amplifier) is presented in this article. The circuit description is very simple, its construction consists of only single MO-CTTA. The hysteresis and amplitude of the output current can be tuned independently/electronically. With mentioned features, it is very suitable to realize in a monolithic chip. The PSPICE simulation and experimental results are depicted, and agree well with the theoretical anticipation. The maximum power consumption is approximately 249 mW at plusmn5 V supply voltages.
