摘要: A reconfigurable complex band-pass (CBP)/low-pass (LP) active-RC filter with a noise-shaping technique for wireless receivers is presented. Its bandwidth among 500 kHz, 1 MHz and 4 in LP mode MHz, 2 8 CBP 3 center frequency. The Op-Amps used the are realized cell arrays order to obtain scalable power consumption different operation modes. Furthermore, can be configured into 1st order, 2nd or 3rd mode, thus achieving flexible filtering property. introduced suppress flicker noise contribution. has been implemented 180 nm CMOS consumes less than mA MHz-bandwidth mode. spot at 100 Hz reduced by 14.4 dB most technique.
