Active-RC channel selection filter tunable from 6 kHz to 18 MHz for software-defined radio |
Abstract | ||
|---|---|---|
An active-RC channel selection filter for SDR is described whose cut-off frequency is tunable from 6 kHz to 18 MHz. This frequency tuning range is sufficient to cover from PDC (25 kHz) to IEEE 802.11a (20 MHz), including the effect of process, voltage, temperature variations. For the wide tuning range, a differential R-2R ladder has been developed which gives widely variable resistance with minimum silicon area. Wide bandwidth operational amplifier (op-amp) is designed to dissipate small power by employing a current re-using feedforward frequency compensation scheme. |
