Abstract:
A priority encoder comprising:a by-pass stack comprising first, second, and third nMOSFETs;a broken stack of nMOSFETs comprising first, second, and third groups, wherein:the first group comprises an nMOSFET having a source coupled to the source of the first nMOSFET in the by-pass stack;the second group comprises first and second nMOSFETs serially coupled to each other, where the second nMOSFET in the second group has a source coupled to the source of the second nMOSFET in the by-pass stack; andthe third group comprises first and second nMOSFETs serially coupled to each other, where the second nMOSFET in the third group has a source coupled to the source of the third nMOSFET in the by-pass stack.
