An electronically controlled current-mode triangular/square wave generator employing MO-CCCCTAs

A new current-mode triangular/square wave generator based on MO-CCCCTAs (Multiple output current controlled current conveyor transconductance amplifiers) is presented in this paper. The circuit description is very simple, its construction consists of 2 MO-CCCCTAs and 1 grounded capacitor without any external resistor. The output frequency and amplitude can be electronically/independently tuned via corresponding input bias currents. With mentioned features, it is very suitable to realize in a monolithic chip. The PSpice simulation results are depicted, and agree well with the theoretical anticipation. The maximum power consumption is approximately 1.62mW at±1.5V power supply.
