A variable threshold voltage inverter for CMOS programmable logiccircuits

摘要

A programmable input threshold voltage inverter compatible withndouble gate transistors fabrication processes is presented. Such ancircuit is useful as a programmable input threshold buffer for generalnpurpose circuits that can he included In both TTL and CMOS environments,nor can be used as low cost analog programmable comparator. A prototypenis fabricated and measured
