Abstract
A DAC cell includes first and second transistors, drain-source coupled at a first node, a gate of the second transistor coupled to a data input (D), and third and fourth transistors, drain-source coupled at a second node, a gate of the fourth transistor coupled to a complement of the data input (DB). The circuit further includes first and second shadow transistors each coupled between the first node and ground, a gate of the first shadow transistor coupled to a switching input (S) and a gate of the second shadow transistor coupled to a complement of the switching input (SB). The circuit still further includes third and fourth shadow transistors each coupled between the second node and ground, a gate of the third shadow transistor coupled to S and a gate of the fourth shadow transistor coupled to SB.
