AbstractThis article presents the square/triangular wave generator based on multiple output voltage differencing transconductance amplifiers (MO-VDTAs). The circuit topology is simple, consists of only two MO-VDTAs and a few grounded passive components. The features of the proposed circuit are that, its amplitude and frequency can be independently controlled by bias current of the MO-VDTAs, which is not dependent on power supply level. The PSpice simulation results are depicted that they agree well with the theoretical analysis. The total power consumption is approximately 14.3mW at ±1.5V power supply voltages
