The utility model discloses an impedance matching circuit. The impedance matching circuit structure is realized through lumped elements. The impedance matching circuit is composed of a parallel PC circuit, two inductors and four capacitors. The loss caused by a resistor and a parasitic channel is ...
Impedance Matching Circuit and Formula To match a specific loadresistanceR with a driving resistance R’ at frequency ω0, we design an L matching circuit as illustrated below. Impedance Matching Circuit Let’s find the admittance (Yin) of the above circuit. Consider that, the Resistor (R) an...
(1)阻抗匹配(matched load):即Z_L=Z_0,在这种情况下,反射系数为0,不存在信号反射 (2)开路(open circuit):开路可等效为负载阻抗Z_L无穷大,此时反射系数近似等于1,即信号几乎完全反射回来,由于反射信号和注入信号方向相反,因此负载上的电流为0。 (3)短路(short circuit):短路可等效为负载阻抗为0,此时反射系数...
Harvesting Circuit to Rechargeable Battery: DC-DC converter We used a “Buck converter” to convert the original matching impedance 400 kΩ to a rechargeable battery level, less than 100 Ω. However, in practice, 400 kΩ became 5 kΩ, 80-time reduction of the matching impedance. We obtained...
