The paper deals with the problem of digital circuit design based on the current-mode gates - novel digital elements operating with a constant, continuous power supply current. The purpose is the provision of a high level noise immunity of chips which contain both analog and digital circuits. The logical properties and several identities of the current-mode logic and some expressions for a conversion of the Boolean functions into the current-mode functions are represented. Based on these properties and expressions, the approaches of minimizing the current logic functions are derived. Moreover, a new concept of the low-voltage current-mode gates realization and the two new types of the current-mode gates are designed for the next reduction of the current mode digital circuit complexity. Based on these approaches and new types of the gates, the functional schemes of some current-mode combinatorial and sequential circuits are derived. The obtained circuits are characterized by lower hardware overheads (up to 35%) in comparison with similar hardware based on the classical voltage type gates.
