DESIGNING PROTOTYPE OF THE XILINX FPGAs FUNCTION GENERATOR WITH THE CURRENT-MODE GATES

The paper deals with the problem of designing main FPGA-cell blocks with the current-mode gates – novel digital gates operating with constant, continuous power supply current. Using proposed approaches to designing digital current-mode circuits, the currentmode prototypes of several digital circuits and the main basic block of FPGA cell – the function generator – are designed. The obtained circuits are characterized by smaller hardware overheads and switching noise level in comparison with the similar circuits based on the classical voltage type of gates. It proves the possibility of realization of field programmable mixed analog-digital array on a single die.
