چکیده
In this paper, a low voltage ultra-wideband RF receiver for Software-Defined Radio (SDR) is presented. In SDR design, the radio frequency (RF) receiver should be able to receive signals over a broadbandwidth so that it can satisfy a variety of different communication standards. In the proposed design, working frequency ranging from 0.1GHz to 6GHz RF front-end for SDR, covering almost all of mature communication standards, is designed. Implemented in a standard 40nm CMOS technology, the proposed receiver is realized consisting of ultra-wideband low noise amplifier, active mixer, intermediate frequency amplifier and variable gain amplifier. It is able to work in the ultra-wideband while preserving low noise figure and consuming less than 5mW power under a single 1.1-V supply voltage. KeywordsLow voltage; ultra-wideband; Software-Defined Radio

متن کاملBroadband digital direct down conversion receiver suitable for software defined radio
While a significant amount of work has been carried out on digital receivers to support flexible and adaptive high data rate processing for multiple systems, small interest has been shown on the RF part and especially the advantages of using a broadband RF front end. This paper presents a challenge raised in the design of a single flexible multimode and multiband RF receiver. It proposes a new ...
متن کاملEvaluation of Geometric and Atmospheric Doppler for GNSS-RO Payloads
To reduce the sampling rate in global navigation satellite system (GNSS)-radio occultation receivers, it is essential to establish a suitable estimation of Doppler frequency from the received signal in the satellite onboard receiver. This receiver is usually located on low earth orbit satellite and receives GNSS satellites signal in the occultation situation. The occurred Doppler on the signal ...
