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...
This paper presents the design and post-layout simulation results of an integrated differential LNA in a 0.18 mum CMOS process, which operates in the frequency bands of 5 GHz to 6 GHz. It utilizes two cascode stage amplifiers, cascaded with a phase splitter to achieve a differential signal. From a 1.5 V supply, the circuit exhibits a gain flatness of 13 dB with less than 0.08 dB variations within...
