In this paper, a new technique for realizing area-efficient, low-noise filters is introduced. The proposed filter topologies utilize noise shaping techniques to shift the noise of the passive and active filter components out of the passband of the filter. This is illustrated by implementing a programmable noise-shaped post-mixer gain-filtering circuit for a CMOS Mobile-TV tuner. The proposed circuits relax the noise-linearity tradeoff in the receiver chain by providing blocker rejection following the mixer outputs. The filter provides an in-band input referred noise density as low as 7.5 nV/sqrt(Hz). The measured out-of-band IIP3 values are 30 dBV and 31.5 dBV for the 3.8-MHz (DVB-H) and 750-kHz (ISDB-T) modes, respectively. Total current consumption is 5.5 mA from a 1.2-V supply. The gain of the block is programmable to be 0 dB, 8 dB, 14 dB, or 20 dB. The design occupies a die area of 0.28 mm2 in a 65-nm CMOS process covering a frequency band of 700 kHz to 5.2 MHz as a universal mobile-TV integrated baseband gain-filtering solution. |
