Abstract:The minimum-maximum (minimax) circuit selects the minimum and maximum of two input currents. Four transistors in matched pairs are operated in the saturation region. Because the behavior of the circuit is based on matched devices and is independent of the relationship between the drain current and the gate-source voltage, transistor pairs may operate in strong, moderate and weak inversion. Therefore, the circuit can also be implemented in bipolar as well as MOS technology. The circuit has many useful applications in modern signal processing
