STATIC AND DYNAMIC PERFORMANCE OF MICROPOWER TRANSISTOR LOGIC CIRCUITS. PART II. MICROPOWER LOGIC CIRCUIT DESIGN.
Abstract
The report describes the design of six basic saturating logic circuits, including TRL, DCTL, DTL, and TTL, for operation at microampere current levels. The exact worst case design equations are derived and written for each circuit to include component tolerance, device variation with temperature, and immunity to external noise voltage. Mathematical expressions for power dissipation and average propagation delay time are derived from equivalent circuits under nominal operating conditions. With the aid of a digital computer, the range of valid worst case designs is determined. The evaluation of these designs for minimum power dissipation and minimum propagation delay time concludes that DCTL and TTL offer the best overall micropower performance. (Author)
