the operational amplifier must be able to rapidly change the gate-to-source voltage. A MOSFET with high gate-to-source and gate-to-drain capacitances (CGSand CGD, respectively) will require higher drive current to reach a desired slew-rate. Therefore, it is important to...
Besides voltage, resistance and capacitance, analternating currentis also influenced by inductance. 除了电压 、 电阻和电容之外, 交流电还受电感的影响. 期刊摘选 This is analternating currentgenerator. 这是一台交流发电机. 《简明英汉词典》 This symbol means analternating current( AC ) power line. ...
ac circuits are never so simple in real applications. The rms current in an ac circuit with resistance is given by the rms voltage divided by the resistance (“root mean square voltage” means the effective average voltage). Two other elements – capacitance and inductance – come into play,...
2 Similar to resistor voltage noise being converted into current noise by the resistance, the amplifier voltage noise en_dut is converted into current noise by the total input capacitance, which includes the sensor capacitance, board stray capacitance, and the amplifier input capacitance ...
The letters R, L, and C represent, respectively, the values of the resistance in ohms, the inductance in henrys, and the capacitance in farads. The source of the AC electromotive force is located between a and b. The wavy symbol is a reminder of the sinusoidal nature of the voltage ...

The amplitudes and temporal characteristics of both SEJPs and fast EJCs are predicted by the theory, but those of the slow EJCs are not. It is shown that these slow components cannot arise as a consequence of propagation of fast quantal components from their site of origin in the muscle ...
