“…7. According to the circuit design theory, to have a fast and stable circuit, in s-plane, dominant poles of the gain should be placed at a distance to the imaginary axis, so that angles α and β are close to 45° [8]. Consequently, the real part of the gain dominant poles must be close to -f 3dB,L and -f 3dB,H .…”

In this paper, a new pole-zero technique for reducing thermal noise is represented. In the proposed new pole-zero method, by extracting the noise and voltage-gain equations of the amplifier, the zeros of the noise transfer function (TF) are managed, so that they are placed near the poles of the gain TF. Therefore, significant noise reduction is achieved in the condition of maximizing the small-signal gain. The proposed pole-zero management technique is investigated by designing a 4 to 9 GHz ultra-wide-band (UWB) low-noise-amplifier (LNA). The linearity and power consumption could also be taken into consideration as additional design criteria. The proposed UWB LNA benefited from complete input/output matching, average power gain of 13.5 dB, and average noise figure of 1.4 dB. Also, 1-dB compression point and IIP3 are -8.8 dBm and +9.2 dBm, respectively at 6.5 GHz. With 130 nm CMOS technology, the circuit consumes 20 mW from supply voltage of 1.2 V. The area of the chip with pads is 0.145 µm 2 .Keywords-low noise amplifier (LNA); pole-zero management method; noise cancellation; ultra-wide-band (UWB).

In this paper a three stage Active Inductor (AI) based Low Noise Amplifier (LNA) for Ultra Wide Band (UWB) receiver is presented. A fully differential topology has been adopted in order to improve the circuit robustness against unwanted common mode signals. T-coil peaking is used to enhance the bandwidth over the entire Ultra Wide Band frequency range. Active inductor is employed because of its low area, tunable inductance and high quality factor. Simultaneous Noise and Impedance Matching (SNIM) is employed to reduce the noise figure of the design. Resistive source degeneration has been implemented to improve the linearity of the circuit. The proposed LNA is designed using 90nm CMOS technology. The proposed LNA achieves power gain (S 21 ) greater than 12dB throughout the UWB spectrum providing a bandwidth of 4 -11 GHz. The input matching (S 11 ) and output matching (S 22 ) are kept well below -10 dB and -8dB respectively, while the reverse isolation (S 12 ) is less than -43 dB providing a linearity of -6.9 dBm.

“…There are several broadband LNA design techniques using resistive feedback (Seong, Jang, & Choi, 2011;Zhan & Taylor, 2006), dual reactive feedback (Fu & Kuo, 2006), input LC bandpass filtering (Bevilacqua & Niknejad, 2004;Ismail & Abidi, 2004) and common-gate topology (Chehrazi, Mirzaei, Bagheri, & Abidi, 2005;Shim, Yang, & Jeong, 2013). A wideband response can also be designed by transformers (Z. Y. Huang, C. C. Huang, C. C. Chen, Hung, & C. M. Chen, 2009;Meaamar, Boon, Yeo, & Do, 2010;Reiha & Long, 2007). However, having a broadband gain response is unfavourable, because it does not attenuate undesired interference, and thus, stringent linearity requirements are placed on the succeeding stages.…”

This paper presents the design of a 2.5/3.5-GHz dual-band low-power and low-noise CMOS amplifier (LNA), which uses the capacitor cross-coupling technique and current-reuse method with four switches. The proposed LNA uses a single RF block and a broadband input stage, which is a key aspect for the easy reconfiguration of a dual-band LNA. Switching at the inter-stage and output allows for the selection of a different standard. The dual-band LNA attenuates the undesired interference of a broadband gain response circuit, which allows the linearity of the amplifier to be improved. The capacitor cross-coupled gm-boosting method improves the NF and reduces the current consumption. The proposed LNA employs a current-reused structure to decrease the total power consumption. The inter-stage and output switched resonators switch the LNA between the 2.5-GHz and 3.5-GHz bands. The proposed dual-band LNA optimises power consumption by the securing gain, noise figure and linearity. The simulated performance reveals gains of 16.7 dB and 19.6 dB, and noise figures of 3.04 dB and 2.63 dB at the two frequency bands, respectively. The linearity parameters of IIP3 are −5.7 dBm at 2.5 GHz and −9.7 dBm at 3.5 GHz. The proposed dual-band LNA consumes 5.6 mW from a 1.8 V power supply.
