Low power CMOS RF digitally programmable gain amplifiers for dual-band (Band-III and L-Band) DAB/T-DMB receiver IC are implemented using 0.18 mum CMOS process. For a stable operation among large interference situation, it is required to have wide gain range and fine resolution in RF domain. In order to meet such requirements, various programmable gain amplifier architectures are proposed. Also employing...
