  • Analog voltage maximum selection and sorting circuits
    Patent number: 6188251
    Abstract: An analog circuit is provided to output the maximum voltage from among the set of analog voltages produced by a set of voltage sources connected to the input terminals of the circuit. The circuit has a number of output terminals equal to the number of input terminals. For each input terminal there is one corresponding output terminal. From among the set of analog voltages at the input terminals of the circuit, the analog circuit finds which voltage is the maximum voltage, and it produces this voltage at the output terminal corresponding to the input terminal having the maximum voltage, while setting the other output terminal voltages to zero volts. Through parallel processing of the input voltages, the analog circuit finds the largest input voltage. The analog circuit is made from inexpensive and readily available components suitable for large scale integration fabrication.
