Low-voltage switched-current circuits for mixed signal systems

It is shown in the paper that switched-current (SI) circuits are able to operate on the same chip with digital circuits at low-voltage supply. This property is very important for applications in portable devices like digital cameras or cell phones. In this paper the properties of an SI memory cell are presented. Experimental chip in AMS CMOS 0.8 /spl mu/m technology was fabricated. The results of testing are reported.
