“…However, it degrades near lower-frequency region. To achieve high-performance S 11 for the entire band, it is shown in (5) and studied in [8] that the inductor L s1 directly affects the achievable input matching. However, it has been specified in [12] that the source inductor must be optimised to achieve high-performance S 11 .…”

“…1b and c clearly show cascode gain and NF with and without L x against frequency. In absence of an inter-stage inductor L x , simulation results show a gain roll-off problem in the mid-frequency region (6)(7)(8)(9)(10)(11)(12)(13)(14). Although, both the gain and NF improves, when an inter-stage inductor L x is introduced in the cascode topology.…”

“…Thus, improving important figure-of-merits (FOMs), such as, gain and NF under low supply voltage are continuous challenges in the design of UWB LNA circuit. For example, many topologies have been explored in UWB LNA design, such as, resistive feedback [4], distributed amplifiers [5] and cascode topology with current reuse technique [6,8,9]. Resistive feedback has various advantages for wideband amplification including input matching, gain and stability.…”

“…However, more number of inductors can increase overall Si chip area, which can lead to a higher fabrication cost. In various LNA topologies [1][2][3][4][5][6][7][8][9][10][11][12][13], most UWB LNAs have achieved <15 dB of S 21 and an average NF of 5 dB [5,8]. Since, an RF mixer in a directconversion receiver has a high value of NF at low frequencies and the receiver NF is approximately degraded by 3.6 dB because of flicker noise [9].…”

A two-stage common-source (CS) low-noise amplifier (LNA) that uses a forward-body-bias technique in N-type metal-oxide semiconductor devices and intended to achieve a high gain and low power consumption is proposed in this study for ultra-wideband (UWB) applications. Its first stage yields an exceptionally high gain because of high transconductance (g m1 = 16 mS) of the input device. It also shows simultaneous wideband input matching and lownoise figure (NF) characteristics with the aid of source degenerated inductors. A simple source degenerated CS topology with the shunt-peaking inductor L d2 is designed as the second stage to enhance the gain response at high frequencies. Using a standard 90 nm complementary metal-oxide semiconductor process, the proposed UWB LNA achieves a gain S 21 ≥ 20 dB in the frequency range of 3.1-10.6 GHz, while consuming only 12.6 mW power from a 0.6 V supply voltage. The simulation results show a minimum NF (NF min ) below 1.7 dB in the frequency range of 3.1-10.6 GHz and input return loss S 11 < −10 dB in the frequency range of 3.5-10 GHz. When a two tone test is performed with a frequency spacing of 2 MHz, a high value of third-order input intercept point of −8 dBm is also achieved.

“…In order to meet the stringent requirements for low power operation, various circuit topologies have been studied [5][6][7][8]. Current-reused technique is widely used to achieve low power in [5], which is attractive compared to other topologies as it features sharing current that led to reduce the power consumption. However, relatively large supply voltage is required due to the stacking architecture of multi transistors, and the performance degrades significantly as the supply voltage decrease.…”

This paper presents a 5.2 GHz ultra low power folded cascade low-noise amplifier at low-voltage operation. By utilizing a forward body bias and folded cascade technique, the proposed LNA can operate at a reduced supply voltage and power consumption. In addition, reactive (transformer) feed-back is adopted to further enhance the LNA gain. The proposed LNA delivers a remarkable gain of 15.3 dB with a noise figure of 0.8 dB, while consuming only 0.8 mW dc power from a 0.6-V supply voltage at 5.2 GHz, the simulated Pin-1dB and IIP3 are -22 and -10.34 dBm, respectively. The results indicate that this LNA is full suitable for the ultra low power application.

This article proposes a low‐voltage, low‐power, low‐noise, wideband receiver front‐end consisting of a low‐noise amplifier (LNA) and a mixer. The LNA stage uses a current‐reuse technique for low‐power consumption and high gain. A switched biasing technique is then used to reduce the flicker noise of the mixer. A bulk injection structure is adopted for low‐voltage operation of the mixer. The proposed receiver front‐end achieves input impedance matching of less than −10 dB from 3.1 to 10.6 GHz, a minimum noise figure of 4.9 dB, and a maximum power gain of 17.7 dB while consuming 8.25 mW from 6.87 mA and 1.2 V. This receiver front‐end is fabricated using a 0.18‐μm CMOS process. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:278–281, 2012; View this article online at wileyonlinelibrary.com.
