WebTo develop further intuition in Q-factor and extend its application to matching and bandwidth, it is prudent to study time domain behavior of LC tank. We show how an LC tank starts up, how the voltage developed across it heads to infinity, how a finite Q-factor limits its growth, and what happens if you excite the tank with non-resonant ... WebThe ratio of the capacitor (or inductor) voltage to the applied voltage is the “Q” factor. Q = VL/VR = VC/VR REVIEW: The total impedance of a series LC circuit approaches zero as the power supply frequency approaches resonance. The same formula for determining resonant frequency in a simple tank circuit applies to simple series circuits as well.
