Dear Nordic Engineering Team,
I am currently developing a wireless ECG acquisition system based on the ADS1298 analog front end (AFE), the nRF5340 SoC, and the nRF7002 Wi-Fi 6 companion IC. The goal of this project is to interface the nRF5340 with the ADS1298 to acquire the 12-lead ECG signals in real time and transmit them over Wi-Fi, utilizing the nRF7002 Wi-Fi 6 companion IC.
The system is composed of two custom-designed sections:
- Analog front end, including the power management circuit, input protection, and the ADS1298 AFE.
- Digital section, featuring the nRF5340 SoC for processing and the nRF7002 for wireless transmission.
I have completed both the schematic and a multi-layer PCB layout. Given the complexity of the design , I would be grateful if your team could kindly review the schematic and layout and share any feedback or suggestions for improvement before final validation. Please find the schematic and PCB documents attached
Additional details:
- COEX is not required, as Wi-Fi is used exclusively for data transmission.
- The system is configured for normal voltage mode, with DVDD powered at 1.8 V.
Thank you very much for your time and support. I look forward to your insights.
Best regards,
Abdelrahman
