Off-Chip Inductorless Medical Implant Communication Service (MICS) Band Receiver
Abstract

The invention pertains to a Medical Implant Communication Service (MICS) band receiver, which integrates a mixer circuit and a low noise amplifier (LNA) stacked together and operating with a shared bias current. The system also includes an intermediate frequency (IF) filter and an IF amplifier that operates at multiple amplification levels to generate an IF signal. This design aims to minimize power consumption and reduce the physical size by eliminating the need for off-chip inductors.

Societal Impact

The technology promises to significantly improve patient quality of life by extending the battery life of implantable medical devices, reducing the frequency of surgical interventions, and ensuring reliable real-time health monitoring. This can lead to better healthcare outcomes and potentially lower healthcare costs.

Salient technical features and Advantages of the Technology
  • Stacked mixer circuit and LNA operating with the same bias current. 
  • Double balanced mixer circuit with multiple transistors for RF signal processing. 
  • Second order RC low pass filter as the IF filter. 
  • IF amplifier functioning at multiple levels of amplification, transitioning from differential amplification to difference amplification to obtain the IF signal.


  • Off-chip inductorless design reduces bulkiness and complexity. 
  • Stacking the mixer over the LNA optimizes the form factor. 
  • Lower power consumption enhances battery life, reducing the need for frequent replacements. 
  • Improved patient comfort and reduced surgical interventions for battery replacements.
