Traditional MICS band receivers in implantable medical devices have high power consumption, necessitating frequent battery replacements through surgeries, and utilize bulky off-chip inductors, leading to complex and unwieldy designs.
Flowchart of Technology
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.
- 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.
The prototype would include a compact MICS band receiver with the stacked LNA and mixer, integrated IF filter and amplifier stages, designed to fit within implantable medical devices while ensuring efficient power consumption and signal processing capabilities.
Experimentation and Testing of the prototype complete successfully.
