中文摘要	a low-power, highly linear, multi-standard, active-rc filter with an accurate and novel tuning architec-ture is presented. it exhibits 1eee 802. 11a/b/g (9.5 mhz) and dvb-h (3 mhz, 4 mhz) application. the filter exploits digitally-controlled polysilicon resistor banks and a phase lock loop type automatic tuning system. the novel and complex automatic frequency calibration scheme provides better than 4 comer frequency accuracy, and it can be powered down after calibration to save power and avoid digital signal interference. the filter achieves oip3 of 26 dbm and the measured group delay variation of the receiver filter is 50 ns (wlan mode). its dissipation is 3.4 ma in rx mode and 2.3 ma (only for one path) in tx mode from a 2.85 v supply. the dissipation of calibration consumes 2 ma. the circuit has been fabricated in a 0.35μm 47 ghz sige bicmos technology; the receiver and transmitter filter occupy 0.21 mm~2 and 0.11 mm~2 (calibration circuit excluded), respectively.
