WebThe self-resonant frequency of the capacitor is the frequency at which the reactance of the capacitor (1/ωC), is equal to the reactance of the ESL (ωESL). Solving this equality for the resonant frequency yields: 2 ESL C 1 fRESONANCE π ⋅ = . Eq. 1 All capacitors will display impedance curves which are similar in general shape to those shown. WebOct 17, 2024 · V R E = V c c − I C R C − V C E where V C E is equal to the voltage drop across the collector branch, which is given by I C R C to be 2.5V. Add the 0.2V for the saturation voltage to avoid that and you have V C E = 2.7 V. So in the KVL equation above:
WebIn order to reduce power noise, the V CCINT power supply bypass capacitor must be significantly larger than the equivalent switched logic array capacitance. High-frequency bypass capacitors should be 25 to 100 times larger than the equivalent switched logic array capacitance. A factor of 50 will result in a 2 percent variation of V CCINT.
