Design of Low Power Multi-Standard Active-RC Filter for WLAN and DVB-H
In this paper,a low-power,highly linear,integrated,active-RC filter exhibiting a multi-standard (IEEE 802.11a/b/g and DVB-H) application and bandwidth (3MHz,4MHz,9.5MHz) is present. The Filter exploits digitally-controlled polysilicon resister banks and an accurate automatic tuning scheme to account for process and temperature variations. The automatic frequency calibration scheme provides better than 3 % corner frequency accuracy. The Butterworth filter is design for receiver (WLAN and DVB-H mode) and transmitter (WLAN mode). The filter dissipation is 3.4 mA in RX mode and 2.3 mA (only for one path) in TX mode from 2.85-V supply. The dissipation of calibration consumes 2mA. The circuit has been fabricated in a 0.35um 47-GHz SiGe BiCMOS technology,the receiver and transmitter occupy 0.28-mm2 and 0.16-mm2 (calibration circuit excluded),respectively.
