Abstract:
An integrated circuit including a primary operating circuit and an added-function circuit which reduces propagation delays during normal operation of said primary operating circuit, said integrated circuit comprising:said primary operating circuit including an input, an output, a logic circuit having a gate element and being connected between the input and the output, an associated voltage source and a ground; andan added-function circuit including a first transistor, a second transistor and a control path,at least one source logic device in said gate element connected between said voltage source and the output,at least one ground logic device in said gate element connected between said, ground and the output,said first transistor coupled in series between said voltage source and said gate element and having a width of at least two times the width of the widest said source logic device,said second transistor coupled in series between said ground and said gate element, said second transistor having a width of at least two times the width of the widest said ground logic device, andsaid control path selectively enabling or disabling said first and second transistors.
