A Single Supply Standard 8051 Microcontroller based Medical K-grade
Isolation ECG Module with Graphics LCD
Abstract
Electrocardiogram (ECG) monitoring is one of the most important patient
vital sign. Many design for ECG amplifier has been established. In this paper we
describe a unique design of a single supply isolated single Channel ECG amplifier,
based on a standard 8051 micro controller. This micro controller system includes
analog circuit, digital, ADC circuit and graphical LCD. In general, the analogue
circuit module carries out differential amplification, band-pass filtering, power line
interference elimination, and output amplification the digital circuit part consists of
an 8051 standard micro controller, an 8-channel ADC (ADC0808) converter, and
graphical LCD panel. Such system features with low power, low cost and small
size which can be used for home use.
