The paper deals with the problem of design and FPGA-based realization of digital circuits with current-mode gates: novel digital gates operating with constant, continuous power supply current. The purpose is the provision of a high level of noise immunity of chips, which contain both analog and digital circuits. Using the proposed approach to design digital current-mode circuits, current-mode prototypes of several digital circuits and similar to the Spartan II slice are designed. The obtained circuits are characterized by smaller hardware overheads and switching noise levels in comparison with the similar circuits based on the classical voltage type gates. This indicates the possibility of realization of field programmable mixed analog-digital array on a single die.
