A CMOS RF digitally programmable gain amplifier (RF PGA), covering various terrestrial mobile digital TV standards (DMB, ISDB-T, and DVB-H) is implemented as a part of a low-IF tuner IC using 0.18-m CMOS technology. An improvement of 13-dB IIP3 is attained without significant degradation of other performance criteria like gain, noise figure, common-mode rejection ratio, etc., at similar power consumption. This is achieved by applying a newly proposed differential circuit gm (the second derivatives of transconductance) cancellation technique, called the differential multiple gated transistor (DMGTR). In the DMGTR amplifier, the negative value of gm in the fully differential amplifier can be compensated by the positive value of gm in the pseudo differential amplifier which is properly sized and biased. By adopting the DMGTR, a low-power highly linear RF PGA is implemented. Also, in order to have wide gain range with fine step resolution, a new RF PGA architecture is proposed. The measurement results of the proposed RF PGA exhibit 50-dB gain range with 0.25-dB resolution, 4.5-dB noise figure, a 4-dBm IIP3 (maximum 30 dBm) and 25-dB gain at 16-mW power consumption.

“…In 3GPP standard [4], power control performance is regulated as 74 dB range, 1 dB step with +/-0.5 dB step accuracy. The previous works use multiple PGA stages [5] or multiple modulators [3]. The fine/coarse gain control approach degrades gain control linearity and monotonic gain controllability and results in inferior noise characteristics as the input swing of final PGA is recursively decreased with the fine gain control.…”

A single-stage RF programmable gain amplifier (RF-PGA) in 65-nm CMOS is presented. The RF-PGA consists of thermometer-weighted transconductors and binary-weighted transconductors with an R-2R ladder. The transmitter prototype with the single-stage RF-PGA achieves 78 dB dynamic range, 0.27 dB accuracy in 1dB step at 1950 MHz. The measured transmitter noise in RX band is -160.4 dBc/Hz. The ACLR and EVM with LTE modulated signal (BW=20 MHz) are -40 dBc and 3.4 %, respectively.
