Binary MOS parallel comparators

摘要

The monolithic integrated binary MOS parallel comparator uses enhancement-mode insulated-gate field effect transistors of the same conductivity type and comprises n successively weighted stages each including a NOR block having at least two inputs each receiving a correspondingly weighted digit of a different one of a first and a second n-digit binary word and an additional logic circuit also receiving the correspondingly weighted digit of the first and second words, and an output logic circuit coupled to each of the n stages to provide an output signal for the comparator.
