Abstract :
A sub-sampling based multiband RF front end suitable for medical telemetry applications is presented. Using a single inductor and a single sampling frequency it is shown how to downconvert concurrently Bluetooth LE and MICS band signals to baseband with relative attenuation of 42 dB between the two downconverted bands. The proposed front end is analyzed in detail and the results are validated using Spectre RF simulations for a 0.18μm CMOS process.
