A fully integrated receiver MMIC manufactured in a 200 GHz SiGe:C production technology is presented. To simplify the application, the fully differential design is based on a homodyne approach. It comprises polyphase filters, passive power splitters, a Gilbert-based complex downconversion mixer, a three-stage low noise amplifier offering two gain steps, and a three-stage programmable gain baseband...
A low-IF front-end receiver suitable for the IEEE 802.15.4 standard operate at the 2.4-GHz band which was designed in 0.18-μm CMOS technology is presented. In the receiver, a single-input to differential-output LNA is used to save DC current and chip area, folded mixer architecture is used to improve noise performance. The front-end receiver has 7.6 dB of single sideband noise figure (SSBNF), -11...
In most receivers a balanced mixer is used, while the output of the LNA is single ended. The presented phase splitter generates an accurately balanced signal out of a single-ended source. The wide-band circuit consists of two RF transistors and a DC control loop. The circuit operates up to, say, fT/4. In the article the basic circuit is discussed and an IC implementation is given.
A wide band 5.8-10.6 GHz low-noise amplifier (LNA) employing a common-gate stage for wideband input matching is presented in this paper. This LNA is used to work for the upper band of ultra wide band (UWB) wireless receivers according to the DS-CDMA proposal. The feedback technique is used to achieve a large bandwidth around 4 GHz. Moreover, this topology helps to cancel the noise of the input matching...
This paper presents a low-power CMOS RF front-end for 3-5 GHz non-coherent impulse-radio ultra-wideband (IR-UWB) receiver. The proposed front-end comprises a variable-gain low noise amplifier (VG-LNA), an active balun and an analog squarer. Current reuse topology has been adopted in both VG-LNA and active balun to reduce the power consumption. The squarer design is based on the quadratic law of MOSFET...
SMILE (spatial multiplexing of local element) technique is a front-end receiver architecture which uses only one RF channel, carrying multiplexed information from multiple antennas. In this work, a fully integrated LNA (Low Noise Amplifier) in a 0.35 mum CMOS technology with four input channels and multiplex function is presented. The performance characteristics of the LNA such as gain, noise figure,...
