Beta measurement and beta requirement in I/sup 2/L gates

Abstract
A new approach to beta measurement in the inversely operated I/SUP 2/L transistor is described, one that avoids arbitrary definitions and terminal-condition specifications. The authors deactivate the lateral p-n-p by symmetrical biasing so that direct measurement of n-p-n base current becomes possible. Further measurements demonstrate the validity of this approach, and also determine the beta necessary for a desired saturation voltage.
