Design Consideration for LPF with Gain Boosting in GHz-Range Applications Conference Paper

abstract

• a 0.18 m CMOS fifth order Butterworth low-pass filter with 24dB programmable gain boost at its 1.2 GHz cut-off frequency for HDD applications is presented. A new Gm-LC architecture is proposed using feedforward path techniques to achieve the required boost. The gain of the feedforward path can be controlled to provide the variable boost. Simulation results shows that a 28/46 mA is drawn from a 1.8V supply in the no-boost/max-boost cases respectively. Group delay variations for different boost values are limited to 10% from the no-boost case. At the nominal output voltage swing of 250mVpp at 1.2GHz, a THD of -42 dB is obtained. 2005 IEEE.
