THE DESIGN OF nMOS QUATERNARY FLIP-FLOPS AND THEIR APPLICATIONS
nMOS四值触发器的设计及其应用

By using the theory of clipping voltage-switches, two kinds of master/slave nMOS quaternary flip-flops are designed.These flip-flops have the capability of two-input presetting and double-rail complementary outputs. A modulo-16 up counter and a modulo-10 up counter are designed by using JKLM type flip-flop. It is shown that these flip-flops can be flexibly used to design quaternary sequential circuits.
