TH21262B - A common bias circuit for a discrete type where each has its own bias circuit. - Google Patents

Abstract

This circuit is described for operating discrete integrated circuits from a common bias source. By coupling the DC signal to each bias circuit of the discrete IC together in order to eliminate the capacitor coupling signal. In other cases, to interface between IC diskettes and to isolate bypass capacitors in each biasing. Other Requirements for Desktop ICs
