AbstractThis paper presents an8th order active-RC elliptic low-pass filter(LPF) for a direct conversion China Mobile Multimedia Broadcasting(CMMB) tuner with a1 or4 MHz-3 dB cutoff frequency(f-3dB). By using a novel gain-bandwidth-product(GBW) extension technique in designing the operational amplifiers(op-amps), the proposed filter achieves71 dB stop-band rejection at1.7 f-3dB to meet the stringent CMMB adjacent channel rejection(ACR) specifications while dissipates only2.8 mA/channel from a3 V supply, its bias current can be further lowered to2 mA/channel with only0.5 dB peaking measured at the filter's pass-band edge. Elaborated common-mode(CM) control circuits are applied to the filter op-amp to increase its common-mode rejection ratio(CMRR) and effectively reject the large signal common-mode interference. Measurement results show that the filter has128 dBμVrms in-band IIP3 and more than80 dB passband CMRR. Fabricated in a0.35-μm SiGe BiCMOS process, the proposed filter occupies a1.19 mm2 die area.?2011 Chinese Institute of Electronics.
