I have been studied semiconductor design since 1995 when I was in the junor class of EE.
Following to the professor's recomendation to go on to gratuate school for DSP (Digital Signal Processor) design, I started to study in the laboratory.
It was very suprising for me as I was deeply interested in the programming rather than my major until then. My professor just came from industry. With great passion, he set up his laboratory with seniors and juniors. As he aimed for mixed signal processing, he needed a student very handy at software like me for digital logic design as well as crammers for analog circuit design.
He made huge influence on me with his great insight on analog circuit design and good intuition for system chip design. That is how I can handle semi-custon design and full-custom design as well.
I experienced communication system with GPS (Global Positioning System). I designed the digital correlator which tracks the satelite's signals. As GPS exploits the DS-SS (Direct Sequence Spread Spectrum) modulation, it leaded me to understand CDMA (Code Division Multiple Access) system including rake reciever design and syncronization mechanism.

I programmed FPGA to evaluate on the real GPS system and finally I made it into 5mm x 5mm silicon with IDEC MPW(Multi Project Wafer) using Samsung 0.8um process. It was the birth of my first chip.
Now I think that every thing is on the line. I designed GPS receiver, interested in mobile communication system and developed high-speed interfaces for mobile applications.
