Abstract :
A low-noise amplifier (LNA) fabricated in a standard 0.35 μm AMS CMOS process is described. The LNA is part of a telemetry system which is part of a R&D project for biomedical applications. The goal is to build a low-power 174-230 MHz RF transmitter-receiver suitable for measuring blood pressure on a patient body. The low noise amplifier is composed of transistors only, which allows full integration on a standard CMOS process. The LNA has been measured to have a noise figure of 2.6 dB and a 21.7 dB gain at 200 MHz. The input IP3 is -12 dBm.
