A 0.6 V, low‐power and high‐gain ultra‐wideband low‐noise amplifier with forward‐body‐bias technique for low‐voltage operations

Abstract

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.

Design of ultra‐low noise, wideband low‐noise amplifier for highly survival radar receiver

“…The cascode topology has lot of disadvantages, i.e. it requires a high voltage for biasing of two transistors and consume more power [21]. The cascade topology is a combination of two common-source transistors surrounded by some passive elements for input impedance matching and an interstage passive circuit between both common-source stages to meet the wideband configuration.…”

“…But ‘notch filter technique’ was a new idea for wideband LNA in the 2010s to reject interferers [161, 164, 196, 283] and that was called IRLNA (Interfere Rejection LNA) [196, 283].

A 5- GHz CMOS Low Noise Amplifier with High Gain and Low Power using Pre-distortion Technique

“…As a result of low complexity the effect of parasitics diminished and allow multiband operation.The two stages of LNA are integrated with capacitances and resistances that are parasitic in nature is used to achieve input impedance with real characteristics at the LNA's output in the feedback loop. The good input matching is achieved with high power gain and lower supply voltage [4] and that stages of LNA are suitable for UWB applications. The cascade stages does not support wideband matching, so to overcome this problem the voltage buffer is introduced to achieve low power and input matching.…”
