Abstract
A data selector based on TVD includes two AND gates, an OR gate, and three buffers, wherein the two AND gates and the OR gate adopt a three-phase dual-track pre-charge logic as a work logic. The data selector fulfills one time of evaluation operation and has three stages in one cycle. When a discharge control signal and a pre-charge control signal are at low levels, the data selector enters a pre-charge stage. When an evaluation signal is changed to a high level from a low level, the data selector implements the evaluation operation to fulfill the circuit function. When the discharge control signal is changed to a high level from the low level, the data selector enters a discharge state and gets ready for the next evaluation operation.
