Abstract
A low power logic output buffer includes first and second logic gates, each having an input and an output. The input of the first logic gate receives a first logic signal, and the input of the second logic gate receives a second logic signal. The buffer includes first, second, third and fourth n-type metal oxide semiconductor (NMOS). The buffer also includes first and second bias switching NMOS. The first bias switching NMOS is coupled between the source of the third NMOS and ground, and the gate of the first bias switching NMOS is coupled to the output of the first logic gate. The second bias switching NMOS is electrically coupled between the source of the fourth NMOS and ground, and the gate of the second bias switching NMOS is coupled to the output of the second logic gate.
