Abstract :
A 7th-order 0.05° 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 gm -C filter relies on a programmable BiCMOS transconductance amplifier to achieve a 10× programming range of the -3 dB cutoff frequency (0.4-4 MHz) and up to 13 dB of boost
