“…This results in a substantial increase in the die area and implementation costs. In addition, tunable active inductors have been explored in [7,8] to overcome the low quality factor of inductors and their large area consumption on chip. However, the drawbacks associated with the use of active inductor are higher power consumption and nonlinearity [9].…”

this paper presents the design of continuously tunable low noise amplifier with frequency tuning range from 2.2 to 2.8 GHz. The amplifier achieves input matching and tunability through a transformer based input matching network. The proposed circuit uses an inductively degenerated common source cascode amplifier to design the amplification stage. The circuit includes a phase shifter circuit to shift the phase of the input signal to achieve tunability through transformer. The LNA achieves a maximum gain of more than 17dB in the entire tuning range. The LNA attains a perfect impedance match across the tuning range and has a stable operation. In addition, it achieves a low noise figure ranging from 1.4dB to 5.2dB.

In this article, a novel 1.8-5 GHz downconversion mixer is presented. The mixer is designed and simulated using SiGe 8HP 130 nm CMOS process technology. The proposed mixer is implemented by incorporating a double-balanced configuration, active inductor, and current mirror techniques. For performance optimization of the proposed mixer, different algorithms such as the genetic algorithm (GA), inclined plane system optimization (IPO) algorithm, and particle swarm optimization (PSO) algorithm have been used. Compared to existing works, this design shows an enhanced conversion gain (CG), a third-order input intercept point (IIP3), and return loss ( S 11 ) at the expense of the noise figure (NF). Additionally, the design consumes low power and covers a small chip area compared to other state-of-the-art devices. PSO shows the most promising results when compared to other optimization algorithms’ results. According to the measurement results after PSO optimization, the mixer attains a maximum CG of 25 dB, an IIP3 of 4 dBm, and a NF of 5.2 dB at 5 GHz, while consuming only 15 mW of DC power. The mixer operates at 1.2 V and covers 0.8 mm2 die area.

This paper presents the design and analysis of a continuously tunable low noise amplifier (LNA) with an operating frequency from 2.2 GHz to 2.8 GHz. Continuous tuning is achieved through a radio frequency impedance transformer network in the input matching stage. The proposed circuit consists of four stages, namely transformer stage, tuning stage, phase shifter and gain stage. Frequency tuning is controlled by varying output current through bias voltage of tuning stage. The circuit includes an active phase shifter in the feedback path of amplifier to shift the phase of the amplified signal. Phase shift is required to further achieve tunability through transformer. The LNA achieves a maximum simulated gain of 18 dB. The LNA attains a perfect impedance match across the tuning range with stable operation. In addition, it achieves a minimum noise figure of 1.4 dB.
