摘要：In India and in other developing countries many poor people dies due to non-availability of proper health monitoring and health caring systems in hospitals. This is because of the high cost of available health monitoring and caring systems which cannot be afforded by small hospitals or organizations which provide free treatment for the poor people. The basic element in the health monitoring system is amplifier which amplify the biomedical signal to the appropriate level so that it can be detected faithfully by the further signal processing and display system. The aim of this paper is to design and implement a variable gain amplifier for biomedical signal. Variable gain provide the facility to increase or decrease the gain depending upon the acquiring signal and same amplifier hardware can be used for acquiring various biomedical signals. The circuit was simulated on Multisim and the prototype version was built on general PCB.
