8. Amplitude on the EXTAL pin after startup is determined by the ALC block, that is the Automatic Level Control Circuit. The function of the ALC is to provide high drive current during oscillator startup, but reduce current after oscillation in order to reduce power, distortion, and RFI, ...
where k is the coupling coefficient, Q is the quality factor of the coil and 𝑟𝑑rd is the ratio between of equivalent load resistor and coil parasitic resistance. Coil modeling in ANSYS Maxwell is generated as a single-turn coil as shown in Figure 9, and the coil size and ferrite co...
Any vessel on board a CubeSat is restricted to a maximum pressure of 0.12159 MPa (1.2 atm) [1] and must incorporate a minimum safety factor of 4 for the vessel. This restriction has a detrimental effect on thrusters which require pressure differential potential energy to generate thrust and ...
The power factor of an AC circuit is defined as the ratio of the real power (W) consumed by a circuit to the apparent power (VA) consumed by the same circuit. This therefore gives us: Power Factor = Real Power/Apparent Power, orp.f. = W/VA. What does apparent power mean? :the p...
For the present sequence, it is assumed that the input impedance of the transistor remains constant and so a 3 dB decrease of input power corresponds to a factor of √2 reduction in voltage swing amplitude. It is also assumed that the output load con- ditions (and in particular, the ...

The interfacial polarization could lead to a rise in the loss factor in the low-frequency region. The heterogeneity in the CF, with a rise in the BTO content in the PVDF, is also responsible for increasing the loss factor as the BTO. Another possible cause may be from the air voids ...

Discharge time is therefore a crucial factor in energy storage systems and ought to be as low as possible. Here, we used an RC circuit to test the discharge time, speed, and W of 0.05BF-0.35BMT-0.6B ceramics. The samples were connected to the load resistance (1000 Ω). Figure 7a,b ...
