Low power CMOS current source for shortened square wave signals

Abstract

The paper gives short overview of an efficient CMOS technology based current source realization and layout design. The current source output will be shortened square wave signal [1],[2] and [3]. The output current value can be selected from range 5 to 100µA. The current source layout design needs good matching, the geometry and temperature influence has been analyzed and the optimal geometrical structure will be suggested.
