Here, I derive the Curie-von Schweidler law from a series combination of a resistor and a capacitor with a linearly time-varying capacitance. This may possibly be its first derivation from physical principles. However, this required a modification of the traditional charge-voltage relation of a...
The kinetics of the M-current and membrane capacitance are sufficient to produce both voltage oscillations and resonant behaviour. The kinetics of the K+ current by itself is sufficient to produce resonance behaviour (typically observed at depolarized levels). Within the model, the Na+ current ...
L and capacitance C, Bl is the force factor, and ω is the angular frequency. In this work, a metal-oxide-semiconductor field-effect transistor (MOSFET) is introduced to connect or disconnect the shunt circuit using a pre-defined time sequence as shown in Fig. 1...
Figure 2(b) shows the NEGF calculation as a solid line and the fit via the red dots. The perfect fit gives us the parameters τ ≈ ħ/Γ which further strengthens our resistance-capacitance circuit model. This is because in an open dissipative quantum system one expects the ...
The influence of type JD116 motor winding voltage distribution caused byrising time,induction,capacitance and so on is investigated. 建立了变频电机单相绕组的等效电路模型,通过MATLAB/Simulink平台进行等效电路模拟仿真,研究了上升沿时间、电感和电容等参数对JD116型牵引电机定子绕组电压分布的影响。

Compare (2.3) and see footnote 4 on p. 15. 8. This is in contrast with the buffers after the T&H switch, as these have relaxed speed requirements due to the interleaving [26]. 9. Depending on the architecture, the capacitance increases between 4 and 8 times more per bit. Bibliography ...

Another necessary precaution is to compensate the effect of the unavoidable parasitic capacitance Cp (due to contacts, cables, chuck) on the measured reverse current Ime [13]: (6.5)Ime=IR+Cp⋅dVAdt The sharper the voltage ramp, the higher the measured current, as shown in Fig. 6.6. The...
where q = charge at time t, q0 = initial charge, and τ = time constant = RC = ερεoρ, where εo = relative permittivity of free space,ερ = relative permittivity of the medium, ρ = resistivity, R = resistance, and C = capacitance. τ is known as the characteristic decay ...
