Most inverters designed to date can only perform either voltage-buck or boost operation with buck-boost mode usually attained by introducing additional active semiconductor devices and passive components to the inverters. Although effective, adding active switches will complicate the inverter control, and push up the overall system costs.

A Distributed Triband Impedance Matching Network Based on Multiresonant Networks
Circuits, Systems, and Signal Processing, 2021In the RF multiband applications, particularly in multiband power amplifiers, it is necessary to generate well-defined impedances at different frequencies in order to obtain the target output power. In this paper, the design, implementation and evaluation of a concurrent distributed triband impedance matching network for operation at 2.4 GHz (Bluetooth)

Explicit form for impedance of cauer networks
International Journal of Computer Mathematics, 2001In this paper a new procedure is established to obtain in closed form the poles and zeros of the impedance function of a first Cauer Network. The technique involves the continued fraction representation of the corresponding Laplace transform as a rational function whose numerators and denominators can be represented by tridiagonal determinants.

ANTENNA IMPEDANCE MATCHING WITH NEURAL NETWORKS
International Journal of Neural Systems, 2005Impedance matching between transmission lines and antennas is an important and fundamental concept in electromagnetic theory. One definition of antenna impedance is the resistance and reactance seen at the antenna terminals or the ratio of electric to magnetic fields at the input.

Tunable impedance matching network
2007 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference, 2007This work presents a RF tunable impedance matching circuit. It uses a quarter-wavelength (lambda/4) transmission line loaded by a combination of switches, capacitors and inductors. With MEMS-based switches and inductors, the simulation results show that this circuit is capable of correction load reflection coefficients of up 0.5 to better than 0.38 ...
