Wireless medical body-area networks are used to connect sensor nodes that monitor vital parameters. The radio consumes a large portion of the sensor energy budget, and hence its power dissipation should be minimized. The low-noise amplifier (LNA) is an important component of the receiver, and must guarantee low-noise amplification and impedance matching. In this work, an ultra-low-voltage ultra...

This paper presents a low voltage 2.8–11.2GHz CMOS broadband low noise amplifier (LNA) using folded common-gate (CG) topology. The broadband input matching is achieved by adopting CG topology. Bandwidth extension is proposed by inserting an inductor to create a broadband band-pass characteristic with a choke inductor. A folded topology is employed to reduce the supply voltage and thus power con...
