External Component Value Calculations
The external capacitors required for each band in the LC7527E are the structural elements in semiconductor inductors
(simulated inductors). The remainder of this section presents the equivalent circuits and the formulas used to determine
the center frequencies.
1. Semiconductor Inductor Equivalent Circuit
The LC7527E provides circuits with differing constants for the low and high bands.
2. Calculation Example
Specifications: 1) Center frequency: Fo = 63 Hz
2) Q at maximum boost: Q+12 dB = 1.05
Derive the sharpness Qo of the semiconductor inductor itself.
Qo =
× Q
+12 dB ≈ 4.064
See the internal equivalent circuit figure for R4.
Derive C1.
C1 = 1/2
πFoR1Qo ≠ 0.953 (F)
Derive C2.
C2 = Qo/2
πFoR2 ≠ 0.034 (F)
3. Sample Values for C1 and C2
