The low power MICS band biotelemetry architecture and its LNA design for implantable applications

Subthreshold Frequency Synthesis For Implantable Medical Devices

“…Although it was officially established in 1999, the MICS band did not receive significant attention from the academic and research communities until almost 2006. Taking into consideration the main design constraints of IMDs, namely ultra-low power consumption to increase battery life and maintaining acceptable RF performance (phase noise, spurious tones, bandwidth and transmit power), several designs for transmitters, receivers, antennas [16], [17], low-noise amplifiers [18], [19], voltage-controlled oscillators and PLL frequency synthesizers have been proposed which attempt to address these criterion. The scope of this work is limited to the voltage-controlled oscillator and PLL frequency synthesizer, and an overview of recent publications in this area will be discussed.…”

Design and implementation of a voltage-controlled oscillator for MICS-based sensor network system

“…The MICS frequency band spans 402–405 MHz, with an overall bandwidth of 3 MHz, and a channel bandwidth of 300 KHz, allowing wireless communication between medical devices, thus providing increased comfort, mobility, and quality of patient care services [1–3]. The 402–405 MHz frequency band is conducive to wireless signal transmission, and the propagation characteristics of the band are such that signals in this range do not constitute a significant physical risk to humans nor are they particularly vulnerable to interference from other signal transmissions.…”
