The electromagnetic interference (EMI) problem can be resolved in different levels in system design, such as package, circuit and gate level. In this work, we propose and validate a digital logic gate design method to improve EMI performance of digital circuits. We propose one-sided hysteresis dynamic threshold MOSFET (DTMOS) Schmitt Trigger (S. T.) logic gates that can be implemented in standard...
This paper presents subthreshold digital circuit design and optimization method using Schmitt trigger logic gates for enhanced electromagnetic immunity. The proposed Schmitt trigger logic gates are based on a buffer design using dynamic threshold-voltage MOS for low-power operation. By expanding the Schmitt trigger to NAND/NOR gate, we can dramatically improve the noise immunity with much lower switching...
This paper presents several Schmitt trigger logic gates with enhanced noise immunity using variable threshold voltage technique for sub-threshold voltage operation. The proposed logic gates are based on buffer design using dynamic threshold voltage MOS (DTMOS) for low power operation (Vdd=0.4V). Our solution dramatically improves noise immunity of logic gates with much less switching power consumption...
