Design of an Instrumentation Amplifier for a Mobile Electrocardiogram Recorder with Autonomous Power Supply

Modern advances in electronics, as well as circuit and system engineering based thereon have allowed significantly expanding the range of mobile devices with autonomous power supply. Such devices are called gadgets, meaning a novel tool, usually intended for personal use. Gadgets for sports, such as, various smart bracelets, fitness trackers, smart watches, etc. have gained rapid popularity. Meanwhile, it is not difficult to see that the very ideology of gadgets, as devices for a specific individual, is a good basis for creating wearable, autonomous functioning medical electronic devices. This paper considers characteristics of an instrumentation (measuring) amplifier design for a modern mobile electrocardiogram recorder with autonomous power supply.
