LC75386NE
External Capacitor Calculations
The LC75386NE external capacitors are the structural components in semiconductor inductors, i.e. simulated inductors.
This section presents the equivalent circuit and the formulas used to calculate the desired center frequencies.
Semiconductor inductor equivalent circuit
Sample calculation
Specifications: 1. Center frequency: F0 = 100 Hz
2. Q at maximum boost: Q+12dB = 0.9
Determine the sharpness, Q0, of the semiconductor inductor.
(R1 + R4)
Q0 = ————— × Q+12dB ≈ 1.53999
R1
Determine C1.
C1 = 1/2
π F
OR1QO ≠ 1 ( F)
Determine C2.
C2 = QO/2π FOR2 ≠ 0.036 (F)
Note: See the tone control block equivalent circuit diagram in page 15 for the internal resistance.
