Abstract
This paper presents a novel CMOS current source suitable for low voltage applications. The new design shows better compliance voltage than the simple two transistor current mirror while offering improved accuracy and output impedance, featuring 140 KΩ output resistance at an output voltage of 30 mV and output current of 30 μA. The circuit has been manufactured in a 0.25 μm, 2.5 V power supply digital CMOS process from STMicroelectronics.
