Abstract:
A method of manufacturing a device for counting a number of like signals in a plurality of data bits, comprising:a) providing a first plurality of signal paths comprising a true signal path and a complementary signal path for each of N data bits;b) providing a first plurality of transfer gates, each of the first plurality of transfer gates comprising two terminals and a control input, whereby application of a signal to the control input of a given one of the first plurality of transfer gates enables opening and closing of a connection between the two terminals of the given one of the first plurality of transfer gates;c) interconnecting a first signal source to a first plurality of one-hot outputs via the first plurality of transfer gates by forming a first plurality of series paths between the first signal source and the first plurality of one-hot outputs, each of the first plurality of series paths comprising a subset of the first plurality of transfer gates which are connected via their terminals; andd) connecting ones of the first plurality of signal paths to ones of the control inputs of the first plurality of transfer gates by:i) connecting a different one of the first plurality of signal paths to the control input of each transfer gate forming a given one of the first plurality of series paths;ii) connecting a different subset of the first plurality of signal paths to the control inputs of transfer gates in each series path of the first plurality of series paths; andiii) connecting a same ratio of true signal paths for the N data bits to complementary signal paths for the N data bits to the control inputs of transfer gates in each series path of the first plurality of series paths which interconnects the first signal source to a given one of the first plurality of one-hot outputs.
