Impedance controller and impedance control method |
摘要 |
An impedance controller includes a current mirror section to generate an impedance current. At least one detector includes a transistor array and an impedance corresponding to the impedance current, the at least one detector operating responsive to a code generator. And an at least one code generator generates a first code to adjust a gate voltage of the transistor array by comparing an output of the at least one detector to a reference voltage and generates a second code to adjust a size of the transistor array by comparing the output from the at least one detector to the reference voltage.
