Adaptive impedance matching network |
摘要 |
An adjustable impedance matching network for providing an adjustable matching impedance (Rm) is presented. The matching network includes first and second impedance adjusting circuits. The first impedance adjusting circuit is adapted to adjust the value of an imaginary part of the matching impedance while substantially maintaining the value of a real part of the matching impedance based on frequency information frequency and a target reference value. The second impedance adjusting circuit is adapted to adjust the value of an imaginary part of the matching impedance to be substantially equal to zero based on the frequency information, so as to adjust the real part of the matching impedance to be substantially equal to the target reference value. |

1. An adjustable impedance matching network for providing an adjustable matching impedance, the matching network comprising:
a first impedance adjusting circuit configured to adjust the value of a real part of the matching impedance whilst changing the value of an imaginary part of the matching impedance based on frequency information and a target reference value; and a second impedance adjusting circuit configured to adjust the value of the imaginary part of the matching impedance to be substantially equal to a predetermined value. |
