    • Abstract

       

      This paper describes anAnd-or-Invert module developed for theOldap computer designed and being built at the Tata Institute of Fundamental Research. To obtain the maximum speed out of available transistors, the circuit makes use of antisaturation and anti-cut-off techniques. The effect of different components on the transient response of the circuit is described. Detailed results of DC tolerance analysis and noise margins are included. The module which uses only indigenous components should be useful in any general digital system where speed is an important requirement.
