Abstract :
An RF digitally programmable gain amplifier for a terrestrial mobile digital-TV (terrestrial digital multimedia broadcasting, integrated services digital broadcasting-terrestrial, and digital video broadcasting-handheld) is implemented using 0.18-μm CMOS technology. In order to attain a large gain range with fine step resolution, various new programmable gain amplifier architectures are proposed and verified by measurement. The fabricated integrated circuit shows 2.5-dB NF, -20-dBm IIP3, 45-dB voltage gain at highest gain mode in UHF band case, and 78-dB gain range with 0.4-dB resolution while consuming 15mA at 1.8-V supply voltage.
