Abstract :
In this paper, the transistor-level layouts and the experiment results of the down literal circuit (DLC) and the analog inverter (AINV) on a CMOS double- poly silicon process are presented. DLC and AINV are the voltage-mode circuits to realize the down literal function with a variable threshold and the inverse function, respectively. Through the experiment of test- production LSI chips, the good transfer characteristics of DLC and AINV are confirmed. For instance, the threshold voltage of DLC is in error by less than 0.03[V] only. AINV achieves the high linearity within 86% of all signal range and the errors of the output voltage are within +0.01 [V] and -0.11 [V]. The results fully satisfy the requirements for the 5-volt 6-value logic circuits or more. And, the voltage comparator is taken up as an application of DLC and AINV.
