Abstract:
A voltage selector comprising:a plurality of first stage transfer gates including first and second groups of transfer gates, the first group of transfer gates being provided on a first signal transfer path and the second group of transfer gates being provided on a second signal transfer path, one of said first stage transfer gates transferring an input signal in response to a first select signal; anda plurality of second stage transfer gates including a first transfer gate connected to said first group of transfer gates on the first signal transfer path and a second transfer gate connected to said second group of transfer gates on the second signal transfer path, one of said second stage transfer gates receiving and transferring an input signal, transferred from an associated one of said first stage transfer gates, in response to a second select signal,the number of said second group of transfer gates on the second signal transfer path being smaller than the number of the first group of transfer gates on the first signal transfer path, and the number of the second group of transfer gates being set such that a load of the second transfer gate being smaller than a load of the first transfer gate.
