This work proposes low noise amplifier (LNA) and local oscillator (LO) co-design considerations for low intermediate frequency (IF) receivers (RX) in the Medical Device Radiocommunication (MedRadio) band (401-406 MHz), which is used for biomedical applications. Supported with the analysis, proposed considerations are the experimental outcomes of measurements and characterization of fabricated ICs,...
This work presents design and practical techniques to measure specifications of a low noise amplifier (LNA) in a complete receiver chain at Medical Device Radio Communication (MedRadio) band in 401–406 MHz frequency range. Supported by detailed quantitative explanations, the proposed measurement methods help in characterizing the LNA without duplicating it on the chip only for the characterization...
This paper presents a binary frequency shift keying (BFSK) demodulator for low intermediate frequency (IF) receivers and an FPGA based bit error rate (BER) measurement platform for the same. The custom made demodulator is fabricated in 180 nm CMOS mixed mode technology, which occupies an area of 0.09 mm2 and consumes 80 μW power from 1.8 V supply. When integrated with a low IF (2 MHz) receiver front...
