چکیده:

A CMOS modular high-resolution and low-power voltage-mode Maximum circuit is presented. The proposed technique also allows straightforward implementation of Minimum circuit. In this structure a latched comparator circuit is used to determine full-level logics to recognize the maximum voltage between two input voltages. This comparator uses a positive feedback mechanism to generate the analogue input signal in to a full- scale digital level. Then with some transmission- gates the maximum voltage is placed at the output of cell. The circuit has been implemented in 0.35μm standard CMOS technology with 2 volts power supply. Simulation results determine a maximum clock frequency of 167MHz for comparator with 1mv Maximum circuit resolution and 100μw power consumption per cell.
