Abstract
An impedance match circuit having high precision without being affected by variations in manufacturing processes. The impedance match circuit includes an impedance detect circuit, a current comparator, successive approximation controller, and an impedance combination circuit. The impedance detect circuit detects an external impedance. The impedance combination circuit outputs an output impedance. The current comparator compares currents from the impedance detect circuit and the impedance combination circuit. The successive approximation controller realizes whether the output impedance achieves a corresponding impedance match value of the external impedance by the current comparator. If the output impedance does not achieve the desired impedance value, the successive approximation controller will sequentially control the impedance adjusting mechanism in the impedance combination circuit to change output impedance of combination impedance circuit for achieving the desired impedance value corresponding to the external impedance.
