Wideband and low noise CMOS amplifier for UWB receivers

This article describes a low‐power RF front‐end for digital video broadcasting–satellite services to handhelds (2.17–2.2 GHz) implemented in UMC CMOS 90‐nm process. This receiver includes a resistive feedback low‐noise amplifier and a double‐balanced Gilbert mixer. Measurements show a conversion gain of 24.1 dB, a 3‐dB noise figure, an input return loss of −11.9 dB, and an output compression point of −2.2 dBm. This combination draws 12.4 mW from a 1.2 V supply. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:528–531, 2014

“…Figure shows the schematic of a common feedback LNA . The voltage gain of the amplifier is approximately given by

A_{V} = \frac{R_{L} (1 - g_{m 1} R_{F})}{R_{F} + R_{L}}

where g m 1 is the transconductance of M 1 , R F is the feedback impedance, and R L is the load impedance.…”

“…An efficient method to reduce the size of the conventional linear wire antenna is to bend a wire into some geometrical configurations, such as mender line structure [6,7]. The meander line structure is very efficient for the miniaturization of the antenna because of its surface filling property.…”

A low power consumption and high gain ultra-wide-band (UWB) low noise amplifier (LNA) utilizing a common-gate stage connected with a common-source stage by using current-reused structure is proposed. The implemented LNA exhibits a maximum power gain of 14.2 dB with a total (core) power consumption of 7.2 mW (3.8 mW) under a 1.5 V power supply. A minimum noise figure of 4.1 dB was obtained within 3-dB bandwidth of 2.7-8.2 GHz. The proposed UWB LNA presents the highest ratio of the power gain to power consumption among the compared papers. ABSTRACT: An improved wideband planar inverted-F antenna (PIFA)is investigated in this work. The meander line structure is introduced into the conventional PIFA and significant bandwidth improvement can be observed. Two improved PIFA antennas with different meander line structures are designed and fabricated; the measured results show good agreement with the simulations, demonstrating 23.1 and 40% bandwidth at Ϫ10 dB return loss, about 131 and 300% bandwidth enhancement, respectively, compared with the original PIFA (less than 10%). Obviously, the proposed antenna demonstrates good performances (especially in bandwidth), compact size, low profile, and low cost; it is thus expected to find possible applications in wireless communication systems.

“…One of these methods uses two common source stages with different resonance frequencies to achieve low power consumption for LNA with high bandwidth [5]. Another method uses two common source and shunt feedback stages to achieve low noise amplifier with good bandwidth, low power and low noise figure [6]. Our design of the proposed ultra-wideband low noise amplifier is based on using three stages amplifier.…”

Nowadays, for the field of wireless communications, the good design of radio frequency receiver for wireless communication applications is considered one of the main targets in radio frequency research. In ultra-wideband (UWB) receivers, low noise amplifier is considered the most important building block in UWB receiver structure. In this paper we provide the design and simulation of ultra-wideband low noise amplifier to get radio receiver with good performance in wireless communication application. This paper introduces the design and simulation of ultrawideband low noise amplifier using 130 nm CMOS technology. This design uses three stages amplifier. The design provides bandwidth range from (3.9 GHz to 15 GHz) with power gain (S 21 ) of 10 dB. The output noise of the proposed amplifier is 300 uV rms . The proposed LNA is designed using 1.2 V power supply, the dissipated power of the proposed amplifier is 1.2 mW. The proposed amplifier gives noise figure of 1.5 dB and input referred third order intercept point (IIP3) reached to 20 dBm.
