ABSTRACT:
A voltage selector for a D/A converter compensates for varying output response times for different value input signals due to variations in signal line lengths. The voltage selector includes a plurality of first stage transfer gates, including first and second groups of transfer gates, and a plurality of second stage transfer gates, including a first transfer gate connected to the first group of transfer gates and a second transfer gate connected to the second group of transfer gates. The number of the first group of transfer gates is greater than the number of the second group of transfer gates and the number of the second group of transfer gates is set such that a load of the second transfer gate is smaller than a load of the first transfer gate.
