An ultra-low power adjustable triangle wave generator with a multi tunable amplitude and frequency is introduced in this paper. The proposed circuit consists of a Schmitt trigger and a current source. The overall nonlinearity of the TWG circuit is less than 2% in its current-to-frequency transfer characteristic. The tunable frequency and amplitude range are 10KHz to 40KHz and 0.1V-1.7V respectively. The topology is suitable for VLSI realization and can be used in the WINeR system.
