A seventh-order g(m) - C filter with bicubic section for pulse slimming
A 7(th)-order 0.05 degrees equiripple linear phase filter is presented which includes a bicubic section to perform the pulse slimming function required in a magnetic tape drive read channel. The g(m)-C filter relies on a programmable BiCMOS transconductance amplifier to achieve a 10X programming range of the -3dB cutoff frequency (0.4-4MHz) and up to 13dB of boost.
