J. Segura et al., A VARIABLE THRESHOLD VOLTAGE INVERTER FOR CMOS PROGRAMMABLE LOGIC-CIRCUITS, IEEE journal of solid-state circuits, 33(8), 1998, pp. 1262-1265
A programmable input threshold voltage inverter compatible with double
gate transistors fabrication processes is presented, Such a circuit i
s useful as a programmable input threshold buffer for general purpose
circuits that can be included in both TTL and CMOS environments, or ca
n be used as low cost analog programmable comparator. A prototype is f
abricated and measured.
