A neuron-MOS-based dynamic circuit scheme with two-phase clocks for realizing voltage-mode quaternary logic, is proposed. The dynamic quaternary inverter and literal circuits are designed, and the standard CMOS process with a 2-ploy layer is adopted without any modification of the thresholds. In the proposed circuits, the problem of floating output nodes is solved. The proposed circuits have some...
Dynamic circuits using n-channel multiple-input floating-gate MOS(FGMOS) transistors to realize binary and ternary logic are presented. In binary domino circuits, the n-channel FGMOS transistors are used to replace the nMOS logic block to simplify the circuit structure. By using the advantage that voltage signals are easy to be added by means of floating gate in multiple-input FGMOS transistor, a...
Novel differential flip-flops using neuron-MOS transistors are presented, including single edge-triggered flip-flop and double edge-triggered flip-flop. In the new differential flip-flops, a pair of n-channel multiple-input neuron-MOS pull down logic networks is used to replace the nMOS logic tree in the conventional differential flip-flops. The construction of the circuits has been simplified by...
A novel Schmitt trigger with controllable hysteresis using neuron-MOS transistors is presented. By selecting the ratio of capacitive coupling coefficients, a Schmitt trigger with different hysteresis characteristics can be achieved. By only varying the external input control signals, the hysteresis window can be conveniently moved without changing its width. The proposed Schmitt trigger has considerable...
Gravity model has been introduced in several spatial interaction studies, especially in trade relationship, migration and transport activities on different geographic levels. But there is still little research focus on inter-city spatial linkage of innovation activities in a certain region. Within this context, we are seeking to gain a new perspective, while using a developed gravity model and spatial...
