Multiple-valued counter unit based on nerve MOS tube and multi-digit multiple-valued counter

Abstract

The present invention discloses a neuron MOS based multi-valued counter unit. The counter unit includes a neuron MOS source follower and at least a control gate connected the neuron MOS source follower. The control gate includes a first dual-value D flip-flop, a second dual-value D flip-flop, an AND gate, and an OR gate. The present invention utilizes the neuron MOS to replace the complicated threshold value operations of the multi-value logic. The current invention implements the true multi-value logic and a multi-base multi-value counter by increasing the number of the dual-value D flip-flop, and connecting the dual-value D flip-flop to the input control gate of the neuron MOS follower. Comparing to the conventional multi-value counter, the present invention reduces the necessary components in constructing the counter, and it also reduces the cost and power consumption. The present invention applies the asynchronous carry-over concept to implement the multi-digit multi-value counter, and it also has been verified by the simulation of P Simulation Program with Integrated Circuit Emphasis (SPICE).

Description

technical field [0001] The invention relates to a multi-value counter, in particular to a multi-value counter unit and a multi-bit multi-value counter based on neural MOS transistors. Background technique [0002] At present, integrated circuits are developing at a speed exceeding Moore's law, and the scale of circuits that can be integrated on a chip is getting larger and faster. As a result, the power consumption of integrated circuits is increasing. The huge power consumption not only makes various portable devices encounter difficulties in power supply, but also the overheating of chips also makes them prone to work failure and shorten their lifespan. On the other hand, due to the advancement of semiconductor process technology, the area occupied by gate circuits has dropped sharply. On the contrary, in the substrate of VLSI, more than 70% of the silicon area is used for wiring. Therefore, the integration degree of the circuit is limited, the production cost of the inte...

Problems solved by technology

Traditional four-value counters are mostly implemented by four-value D flip-flops and four-value gate circuits, but these four-value components have complex structures and cumbersome designs, resulting in high cost and high power consumption of the counter, which is not conducive to improving the integration of the circuit
