This paper designs a body-biased (BB) differential cascode low-noise amplifier (LNA) with current bias (CR) and capacitor cross-coupling (CCC) technology that meets the bandwidth requirements of 5 GHz wireless applications. In the design, the CCC technology in the differential cascode topology is used to effectively suppress the common mode noise, thereby improving the noise figure. The series resonant network eliminates parasitic capacitance at the input and output ends, thereby improving the power transmission efficiency. The CR technology formed by the intermediate capacitor shares the DC current input to the output device, thereby increasing the gain. This paper uses BB technology in the design to lower the threshold of the cascode device and improve the transconductance, which further improves the gain and reduces the power consumption. The CCC technology used in the paper improves linearity by eliminating the non-linear components present in the input device, which will not interfere with the transconductance of the output stage. This article has obtained excellent performance parameters including gain, noise figure (NF) and linearity without affecting the power consumption, integration and cost of the proposed design.

The calculation and design of an ultralow-power Low Noise Amplifier (LNA) are proposed in this paper. The LNA operates from 5 GHz to 10 GHz, and forward body biasing technique is used to bring down power consumption of the circuit. The design revolves around precise calculations related to input impedance, output impedance, and the gain of the circuit. MATLAB and Advanced Design System (ADS) are utilized to design and simulate the LNA. In addition, TSMC 0.13 μm CMOS process is used in ADS. The LNA is biased with two different voltage supplies in order to reduce power consumption. Noise Figure (NF), input matching (S11), gain (S21), IIP3, and power dissipation are 1.46 dB–2.27 dB, −11.25 dB, 13.82 dB, −8.5, and 963 μW, respectively.
