CMOS Current Reference without Resistance

CMOS Current Reference without Resistance

A micropower current reference can be built with CMOS transistors only. It shows low sensitivity with respect to technology, supply voltage and temperature, and it works on very low supply voltages. The circuit is very simple and occupies a small surface area.
