Abstract :
The present generation of digital integrated circuits is based on the batch-fabrication of interconnected transistors and diodes. These circuits successfully provide the elementary logic modules which can be directly interconnected to realize complex digital systems. The basic circuit configurations and their design must fulfill the prime requirement of signal-quantization under various operational aspects; and thus they reflect compromises between the operation speed, the noise margin, the number of fan-in and fan-out, the operating temperature range, the power dissipation, and the cost of fabricating circuit components to the required tolerance.
