ECL slave reference generator

摘要

A plurality of locally-distributed ECL slave reference generators positioned throughout a large monolithic integrated circuit device for tracking closely a central master reference generator to provide stable slave reference voltages wherein each of the slave reference generators includes a differential comparator which has first and second inputs coupled to a master reference voltage and a slave reference voltage respectively for comparing the master reference voltage and the slave reference voltage and for generating a difference voltage output. A constant current source is coupled to the differential comparator for establishing a constant current flow through the differential comparator. A negative feedback device is responsive to the difference voltage output for supplying a feedback to the second input of the differential comparator as that the slave reference voltage tracks closely the master reference voltage.
