Abstract
A resistor calibration system includes a reference resistor, a first control circuit, a second control circuit, a comparator, a multiplexer and a de-multiplexer. The first control circuit calibrates a first resistor and a duplicated first resistor. The second control circuit calibrates a second resistor. The comparator includes a first input terminal receiving a reference voltage, a second input terminal and an output terminal. The multiplexer includes a first input terminal coupled to the reference resistor and the first resistor, a second input terminal coupled to the duplicated first resistor and the second resistor, and an output terminal coupled to the second input terminal of the comparator. The de-multiplexer includes an input terminal coupled to the output terminal of the comparator, a first output terminal coupled to the first control circuit, and a second output terminal coupled to the second control circuit.
