Synthesis of Energy-Efficient Flip-Flop Circuits Based on Sequential-Parallel Structures of MOS Transistors

Abstract: The synthesis of energy-efficient electronic flip-flop circuits based on the application of arrays of p- and n-channel MOS transistors located in the upper and lower half-planes of the circuit is considered. A method is proposed for synthesizing D, RS, and JK flip-flop circuits using a truth table, direct and inverted minterm maps, and expressions describing the transistor arrays. Variants of circuits with and without an output inverter are considered. It is shown that the synthesized circuits have better characteristics and are more efficient than logic element circuits by factors of 2 to 4. © 2020, Pleiades Publishing, Ltd.
