Abstract
A maximum/minimum value determination apparatus for determining a maximum/minimum value between two digital signals includes two conversion modules each of which receives a first digital signal and a second digital signal and outputs a first analog signal and a second analog signal respectively, where the first analog signal and the second analog signal are respectively linearly related to the first digital signal and the second digital signal. A difference amplifier is connected to the two conversion modules for receiving the first analog signal and the second analog signal and outputting a selecting signal which is either a logical high signal or a logical low signal according to a difference between the first analog signal and the second analog signal. A first multiplexer is adapted to receive the first digital signal, the second digital signal, and the selecting signal and output a maximum of the first digital signal and the second digital signal according to the selecting signal. A second multiplexer adapted to receive the first digital signal, the second digital signal, and the selecting signal and output a minimum of the first digital signal and the second digital signal according to the selecting signal.
