In this paper, a new simple derivation of all stabilizing proportional controllers, for first order linear time invariant systems with time-delay, is presented. Although several results based on the Hermite-Biehler theorem for finding such a set of controllers exist, the aim of this article is to present a shorter and more instructive derivation, which can be followed easily.
