COMPLETED TASKS DURING THE PERIOD

1.Analyze designed new power circuit

After considering electrical protection, patients friendly, high efficiency and etc, we decided to use SMPS as power supply. So we had to design a additional power circuit for the main circuit. It would be designed by using UA741 op amp buffer circuit.
