“…A noise cancelling technique was utilized in References [14,23] with a high power consumption of 9.97 mW and 23.23 mW respectively. CS with an FBB technique was used in References [20,26,27], however, the power consumed by the LNA proposed in References [20,26] was greater than 9 mW and 13.0 mW, respectively. Due to the use of the small power supply LNA proposed in References [27] it consumed less power but had S 11 of ≤−5 dB.…”

“…To mitigate this problem, the forward-body bias technique has been implemented in this paper, to operate the proposed UWB LNA at lower V dd supply of 0.7 V. The transistor M 1 is the key-element in deciding the input impedance matching and noise figure of the complete LNA circuit, and to isolate it from transistor M 2 , the forward-body bias technique has been applied only to M 1 . This provides more degrees of freedom in finalizing the device dimensions of M 2 , to keep transconductance (g m2 ) constant and to provide constant current to primary amplifying transistor M 1 [19][20][21]. The threshold voltage V th of the transistor M 1 can be characterized by:…”

An ultra-wideband (UWB) low noise amplifier (LNA) for 3.3–13.0 GHz wireless applications using 90 nm CMOS is proposed in this paper. The proposed LNA uses an improved common-gate (CG) topology utilizing feedback body biasing (FBB), which improves noise figure (NF) by a considerable amount. Parallel-series tuned LC network was used between the common-gate first stage and the cascoded common-source (CS) stage to achieve the maximum signal flow from CG to CS stage. Improved CS topology with a series inductor at the drain terminal in the second stage connected and cascoded CS third stage provides high power gain (S21) and bandwidth enhancement throughout the complete UWB. A common-drain buffer stage at the output provides high output reflection coefficient (S22). It achieves an average power gain (S21) of 14.7 ± 0.5 dB with a noise figure (NF) of 3.0–3.7 dB. It has an input reflection coefficient (S11) less than −11.7 dB for 3.3–13.0 GHz frequency and output reflection coefficient (S22) of less than −10.6 dB with a very high reversion isolation (S12) of less than −72.4 dB. It consumes only 5.2 mW from a 0.7 V power supply.

In this paper, a CMOS wide-band second-order voltage-mode allpass filter as a time delay cell is proposed. The proposed all-pass filter is made up of solely two transistors as active elements and four passive components. This filter demonstrates a group delay of approximately 60 ps within a bandwidth of 5 GHz, achieving maximum delay-bandwidth-product (DBW). The proposed circuit is highly linear and has an input-referred 1-dB compression point P 1dB of 2 dBm. The power consumption of the proposed circuit is only 10.3 mW. On the other hand, an active inductor is employed in the all-pass filter instead of a passive RLC tank, thereby the three passive components are eliminated, in order to tune the time delay and improve the size. In this case, even though the power consumption increases, the time delay can be controlled across an improved bandwidth of approximately 10 GHz. Moreover, the circuit demonstrates a 1-dB compression point P 1dB of 18 dBm. The proposed all-pass filter is simulated in TSMC 180-nm CMOS process parameters.

This paper presents a low power Low Noise Amplifier (LNA) using 0.18µm CMOS technology for ultra wide band (UWB) applications. gm boosting common gate (CG) LNA is designed to improve the noise performance. For the reduction of on chip area, active inductor is employed at the input side of the designed LNA for input impedance matching. The proposed UWB LNA is designed using Advanced Design System (ADS) at UWB frequency of 3.1-10.6 GHz. Simulation results show that the gain of 10.74+ 0.01 dB, noise figure is 4.855 dB, input return loss <-13 dB and 12.5 mW power consumption.
