Design considerations for transmitter and receiver for personal health care applications
Abstract

This invention is a low-cost, low-power wireless system designed to monitor vital health signs like heart activity (ECG) and blood oxygen levels (SpO2) remotely. It uses advanced technology to send health data from a wearable transmitter to a nearby receiver, which then sends the information to a mobile device like a phone or tablet. This system is reliable and easy to use, making it ideal for early detection of serious health issues, especially in areas with limited access to healthcare.

Uniqueness of the Solution
  • Incorporates an injection inverter between a three-stage and a nine-stage ring oscillator for enhanced signal processing. 
  • Utilizes an edge combiner with symmetric gates to maintain a stable duty cycle for the transmitter output. 
  • Features a receiver with a Local Oscillator (LO) and programmable demodulator for flexible signal reception. 
  • Establishes a reliable wireless communication link in the MedRadio Spectrum band, ensuring minimal power consumption. 
  • Achieves low power and low cost, making the system suitable for widespread use in medical applications.
