Experimental results developed on a fluorescent lamp 32W showed that SRI proposed improved efficiency by 6% compared to the classic SPRI, this is because the SRI does not use a parallel capacitor to the lamp, reducing losses in the cooper of inductance in the
tank circuit LC, the proposed circuit SRI also shows a decrease in the switching or conduction losses on MOSFETs.
As expected due to the
tank circuit from both the external reader and the implant, no coupling between coils was observed at frequencies different from 10 MHz.
However, this article will show that the proper design of the
tank circuit allows the design to meet the phase noise specification.
Orientation of the contact strip does not change the equivalent
tank circuit model, though it will have effect upon the equivalent [L.sub.R] and [C.sub.R] parameters as shown in Equation (9).
The asymmetric structure also possesses an LC
tank circuit above the transmission line.
In this case, the VCO oscillation frequency is close to the self-resonant frequency of the loaded
tank circuit and the phase noise is minimized.
The Q-factor of the
tank circuit is primarily limited by the inductor Q, which is approximately 10 at 5 to 6 GHz.
The close-in phase noise is decided mainly by the loaded Q of the VCO
tank circuit, the flicker noise and the corner frequency of the VCO active device.
The oscillator is obtained by adding a
tank circuit as shown in Figure 6.
