抜粋

We propose a transconductor capable of providing a wide continuous-tuning-range filter applicable to Bluetooth, W-CDMA, LTE, and IEEE 802.11a/b/g W-LANs without sacrificing power consumption or die area. The wide tuning range is achieved without the need for any array configuration, using triode-biased input MOSFETs with transconductance that is widely tunable by means of drain bias adjustment. The transconductor also uses an adaptive DC-blocking circuit that suppresses bias current in a high transconductance mode, which results in minimizing transconductor power consumption.
