(2) high output power, which is proportional to the voltage swing that in turn requires a device with high current and voltage handing capability and low thermal resistance; and (3) high collector efficiency, which in turn requires a device with a usable area in the output I–V curves as...
Where Vdiode = Vthmax(d) + Rd × Icharge, Vthmax(d); Diode turn on threshold voltage, Rd; Diode series resistance As we see in the above equation, the charger requires higher input voltage if the charge current (Icharge) is increased. Below is actual data from an example circuit ...
If there were only constant DC flow in the PDN interconnects from the VRMs to the ICs, that would cause a constant voltage drop, called the IR Drop, between the VRM and the ICs: IR Drop = (Series resistance of the power and ground rails) X (Current in the rails) ……… (PI-1) ...
The typical MOSFET characteristics graph does include the threshold voltage, (VGS(th)) and on-resistance (RDS(on)) vs. temperature. The threshold voltage has a negative temperature coefficient and the on-resistance has a positive temperature coefficient. Figure 2. The electrical characteristics table...
Impedance Resistance to the flow of current in a circuit element, measured as a ratio of voltage across the element and current through the element. Interference The interaction between two waves. The signal wave can interact with other waves that it meets on the way to its destination. A res...
Solving (1) under the condition that the imaginary part of Zinis zero independent of the load resistance Reqresults in the following relationships: Here, the ratio kcapand kindare defined as: Assuming a lossless power conversion: We can calculate the reactance XL1, the inductance ratio kind, th...
In this embodiment, a characteristic impedance (ZT) of each of the first and second transmission portions21,31can be expressed by the following equation: ZT=R0×1+sin2θsinθ, where R0denotes a resistance of the power divider, and is 50Ω in this embodiment, and where θ denotes ...

Diamond is utilized due to its exceptional properties: relatively high refractive index (2.4), wide bandgap (5.5 eV), high mechanical hardness and chemical resistance, and the highest material thermal conductivity at room temperature (2200 W/K⋅m)32,33,34. Consequently, diamond materials, in ...
The results demonstrated that the power generation was correlated with a lower internal resistance and a higher microbial activity. Moreover, chemical results indicated a possible threshold of PCB concentration for the concurrently electricity production and PCB degradation. In fact, PCB removal was ...
