Abstract
A preferred state power-up latch circuit includes first and second cross-coupled P-channel transistors coupled to a first source of supply voltage, first and second cross-coupled N-channel transistors coupled to a second source of supply voltage, the transistors being coupled together to form a latch having an output node, in which at least one of the gate lengths is unequal to the other gates lengths in order to establish a preferred state upon power-up, and the gate width of all the transistors is equal.
