چکیده
A 2 GHz programmable-gain amplifier (PGA) using 0.12-μm CMOS technology is presented in this paper, which has a 51 dB gain control range with 3 dB gain control steps. The maximum output power of this PGA achieves 9 dBm while the 1-dB compression point is located at 8 dBm. A high linearity denoted by the oIP3 of 22 dBm at the maximum gain has been achieved. A new configuration to digitally implement a dB-linear gain characteristic is demonstrated in this paper, which simultaneously enables an adaptive power consumption.

This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
