Abstract

1,078,943. Comparator switching circuits. MINNESOTA MINING & MANUFACTURING CO. Jan. 8, 1965 [Jan. 10, 1964], No. 1003/65. Heading H3T. Inputs 1 and 2 to be compared in amplitude are applied to a 3-stage 2-channel amplifier comprising transistors 28/30, 70/72 and 94/96 of alternating conductivity types operating in emitter-coupled configuration. The last stage has a common emitter resistor 120 across which a signal is developed representing the sum of the input signals. This sum signal is fed back through transistor 124 to supply the emitter current for transistors 28 and 30 and thus reduce amplification for common-mode signals. The collectors of the output stages 94, 96 are clamped to ground by diodes 114, 116 so that the bases of the switching transistors 140, 142 are at ground potential or a negative potential depending on which input is the greater. The collectors are clamped to 4À5 v. negative by diodes 158, 160 so that each output is 0 v. or – 4À5 v. if the corresponding input is respectively greater or less than the other input. Damage by excessively large input signals is prevented by Zener diodes 48, 50.
