Resolving small differential signals across multiple channels
Small signals had to be acquired reliably as part of a compact, battery-powered instrument.
The design considered measurement topology, reference, input conditioning, ADC architecture and PCB implementation together. Battery power, charging, logging, wireless transfer and enclosure fit were integrated into the same architecture rather than added after the analog front end.
The resulting electronic architecture combines precision multichannel acquisition with autonomous power, data logging and Bluetooth connectivity in a compact form factor.
