A Novel Ultra-Wideband CMOS Low-Noise Amplifier for Wireless Communication

摘要

The paper presents the investigation of a novel ultra-wideband CMOS low-noise amplifier for receiver system used for wireless communication. The design is based on a multistage cascade and cascode amplifier cell with a capacitive gain-peaking technique offering gain-enhanced noise cancellation that gives a band of 16.2 GHz, maximum forward gain of nearly 8 dB, NF of 3 dB and impedance matching of nearly 55 Ω is obtained. The proposed architecture is a wideband amplifier in conjunction with the previously proposed cell giving much wider band of 21 GHz. The NF of 1.6 dB is achieved with a maximum gain of approximately 19 dB, while the impedance matching is nearly 50 Ω. The LNA is implemented using design kit in ADS.v.2 2013 platform and 180-nm design technology.
