A 3V 10-100 MHz continuous-time seventh-order 0.05/spl deg/ equiripple linear-phase filter

This continuous-time filter is for high-data-rate read channel ICs. Based on the conventional 7/sup th/-order, 0.05/spl deg/ equiripple, linear phase prototype the lowpass cut-off frequency (Fc) is programmable from 10-100 MHz, magnitude boost is programmable up to 13 dB, and the low frequency group delay can be tuned up to /spl plusmn/30% [1, 2]. Implemented in a 0.29 /spl mu/m BiCMOS technology, the filter has 0.5 mm/sup 2/ core area and dissipates 120 mW at 3 V at 100 MHz.
