Abstract

A CMOS RF digitally programmable gain amplifier, covering various terrestrial mobile digital TV standards (DMB, ISDB-T, and DVB-H) is implemented. 13 dB IIP3 improvement is attained without losing out on other performance criteria like gain, NF, CMRR, etc. at similar power consumption. This is achieved by applying a newly proposed differential circuit gm" cancellation technique. The IC exhibits 55 dB gain range with 0.25 dB resolution, 4.5 dB NF; a -4 dBm IIP3 (maximum 30 dBm) and 25 dB gain at 16mW power consumption.
