A Dual-Band 2.45/6 GHz CMOS LNA Utilizing a Dual-Resonant Transformer-Based Matching Network

Abstract

This paper analyzes and presents design equations for a new transformer-based matching network capable of simultaneously matching two different frequencies. This network is then used to realize a dual-band low-noise amplifier that is fabricated in a 0.13 m CMOS process and is capable of operating at 2.45 GHz and 6 GHz. The measured and noise figure for 2.45 GHz (6 GHz) is 9.4 dB (18.9 dB) and 2.8 dB (3.8 dB), respectively. The IIP3 is measured to be and at 2.45 GHz and 6 GHz, respectively. The power consumption of the system (excluding the buffer) is 2.79 mW from a 1.2 V supply and the total area is m m.Index Terms-CMOS, low-noise amplifier (LNA), multistandard, reconfigurable.

Design of CMOS Dual-band Reconfigurable Low Noise Amplifier for Radar T/R Module

“…Currently, the reconfigurable miniaturized terminals are widely employed in various wireless applications; the different standards or frequency ranges as well as the different signal and modules are used in transceiver, meanwile, in order to increase battery life, the minimum power consumption is required [1]- [2]. For example, in some cases, CMOS transceiver modules need to be freely switched between frequency bands.…”

Transformer-Feedback Dual-Band Neutralization Technique

“…A multiband system can reuse same circuit blocks for concurrent operation at multiple frequencies to lower power consumption, chip area, and system cost. Several techniques have been developed for design and improvement of these circuits, including impedance matching and transformer networks [17]- [19], low-noise amplifiers [20], [21], and power amplifiers [22], [23].…”

Reconfigurable Concurrent dual-band Low Noise Amplifier for noninvasive vital sign detection applications

“…A reconfigurable LNA is realized by making input matching network tunable but it is not a concurrent dual-band system [4]. A Concurrent dual-band LNA is reported in [5] but it is not reconfigurable. In [6], a reconfigurable concurrent dual-band LNA is presented which is having almost constant gain across both bands while operating in mode 3.…”
