This study focuses on a tracking technique for minimally invasive surgery to overcome the possible dangers by endoscopic techniques. We used the principles of electric fields to detect the position of the instrument. With a microprocessor board and a shareware tool known as Processing, a three-dimensional tracking system was developed so that the scalpel inside a patient's body can be monitored by...
This study was aimed to design an electrocardiograph (ECG) system by the 0.35 μm CMOS technology. In this study, a two-stage operational amplifier was taken as the building block for the design of instrumentation amplifier and filters. In our measurement, excellent performance was verified by the fabricated chips.
