... • In a cascade of biquads, H(s) = H1(s).H2(s). …. Before
realization, scale all Hi(s) so that the maximum output
swings are the largest allowable. This takes care of the
output swings of Gm2, Gm3, and Gm5.
• Multiply Gm1 and Gm4, or divide CA, by the desired
voltage scale factor for the internal cap ...
