Abstract

This paper presents a low power, low cost, high integrated transmitter front-end designed for the body area network sensor nodes working at the 2.4 GHz Industry-Science- Medical (ISM) band. Baseband LPF, quadrature up-mixer, differential driver amplifier and T/R switch are designed and implemented in 0.18mum RF CMOS technology. The RC networks based single amplifying block style LPF, modified active up- mixer and two-stage driver amplifier are adopted for large signal processing and low signal distortion. The transmitter outputs OdBm power, with 16dB gain and 8.5dBm 0-IP3, consuming 6mA from 1.8V power supply.
