with given normal center frequencies (0.30kHz, 1.05 kHz, 3.7 kHz, 13 kHz)

a quality factor of 0.9 and adjustable overall voltage gain between 0.2 and 2 for each band

i used the equations f_o= 1/ (2*pi*C sqr R1*R2) and Q = 0.5 sqr R2/R1

i got resistor values of 20k for R2 and 5.1k for R1

my issue is when i plot the overall gain in pspice for each band set at 0.2 i get to high of a gain

any suggestions thanks you in advance
