Abstract
A current switch logic circuit is disclosed. The circuit includes a current sense amplifier formed by a first transistor to a fifth transistor, and a logic tree. The logic tree is used to generate a first current and a second current. The current sense amplifier generates a first output signal and a second output signal according to the first current and the second current.
