An LC filter is disclosed which exhibits excellent attenuation characteristics in a high-frequency range and substantially preserves its self-inductance and Q-factor. The LC filter is constructed of a laminated block formed by laminating insulating sheets each provided with a coil conductor. The coil...

Fig.3 Variations of CPSI with the quality factor under different capacitance ratios 2.2 较大的电流增益及元件参数设计 由于LCLC RC,LCL-T RC等谐振变换器的电流增益为固定的8/Π2,因此根据式(8)可得,使LCCL RC拥有高于普通RC电流增益的必要条件为 ...
L-C filters can be of two types: Choke Input L-section Filter and L-C Capacitor input filter Choke Input L-Section Filter An inductor filter increases the ripple factor with the increase in load current Rload. A capacitor filter has an inversely proportional ripple factor with respect to loa...
Note: A –40 dB gain implies an attenuation of the switching signals by a factor of 100. Peaking20kHz represents the amount of gain at 20 kHz and is related to Q of the LC filter. The drawback to a Butterworth filter for 8 Ω speakers is the use of 33 µH inductors, that are...

An elliptic filter, also referred to as a Cauer filter, is a filter having equalized ripple behavior in both the passband and the stopband. Some implementations combine the strengths of traditional LC filter topologies with advantages of MEMS resonators, including high Q factor. In some ...
For this type of filter, Q = 0.707 = 1 / √2. By substituting Q = 1 / √2 into equations for Cut-off Frequency and Quality Factor previously listed, L and C values can be derived for a critically damped system assuming the desired cut-off frequency, ωo, is known. L = R L ...
Since acoustic resonator filters can provide higher rejection at passband-close frequencies without high edge rolling off loss due to higher quality factor (Q) than LC resonators, a passive non-acoustic filter can be cascaded with a hybrid acoustic LC filter to achieve both wide bandwidth and shar...
