One band switchable low noise amplifier (LNA) is designed for wideband applications. The proposed band switchable LNA has two switchable bands. The design consists of a input matching circuit, two cascode common-source amplifiers and an output buffer for measurement. The proposed LNA is designed with two switching capacitors as loading that use NMOS to make high quality factor. The proposed LNA gives...
This paper presents a dual-band low-noise amplifier (DB-LNA) with switching band groups for WiMedia Ultra-Wideband. The LNA is designed and implemented in TSMC 0.18 μm RF CMOS technology. Measurement results show that the DB-LNA gives 6.1 dB and 9.8 dB power gain, and that input and output matching are lower than -9.3dB/-9.4dB (Group-1/Group-6) and -9.2dB/-11.7dB (Group-1/Group-6). A minimum noise...
