This paper explains the importance of device size and DC bias conditions for the gain and linearity performance enhancement of silicon based RF amplifiers. In this work, the existence of an optimum device size for maximum gain, for the given bias conditions and load impedances is explained by determining the small-signal gain parameters for a common source amplifier as functions of the device size...
This paper describes the design and realization of a balanced low-noise amplifier (LNA) module in the 2 GHz band suitable for wireless infrastructure (base-station) receiver front-end applications. The design effort entails both aspects of MMIC and module/packaging design to realize a fully-matched solution in a miniature 5 mm/spl times/6 mm footprint. The MMIC design leverages Agilent Technologies'...
A 2 GHz programmable-gain amplifier (PGA) using 0.12-/spl mu/m 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 2.4-6 GHz broadband CMOS differential LNA for WLAN and UWB receiver is presented. The LNA is fabricated with the 0.18 /spl mu/m 1P6M standard CMOS process. Measurement of the chip is performed on a FR-4 PCB test fixture. In the UWB low-band (3 to 5.15 GHz), the broadband LNA exhibit a gain of 17.5-18.2 dB, noise figure of 3.4-5 dB, input/output return loss better than 10 dB, and input P/sub 1dB/...
A variable gain amplifier operating at 2.5 GHz based on single ended topology has been designed and characterized. Three such stages were cascaded preceded by a single stage LNA. A source follower is used at the output as an active load matching. Overall dynamic gain variation is 45 dB with a maximum gain of 47 dB. The -3 dB bandwidth is 0.800 GHz. A minimum noise figure of 0.81 dB is obtained in...
