Abstract :
A highly versatile general purpose analog/digital/ neural configurable logic block (LVUC) for utilization in the next generation of mixed signal field programmable gate arrays is reported. The cell is a truly universal building block, very compact and has low power, low voltage requirements and operates with rail-to-rail analog and digital signals. It can be easily configured to perform as a digital, analog, analog to digital, digital to analog and neural configurable block. Experimental results of a fabricated test chip are presented that validate the proposed cell operating with rail-to-rail signals from a single supply as low as 1.4V
