I am a 1.75M, 70Kg hardworking human
. As you can see, I earn my living by working on the computer. I use work station, both HP and SUN. Sometimes, I will work on the PC based system if that is the only tool available. I am a Analog/Mixed signal design engineer.
I am working for an organization called the BlueChip Technology. I am now a principle consultant. There is a saying that the consultant know everything about nothing. I guess that is true, because I am not sure what I know and what I do not know. Prior joining BCT, I worked for Centre for Wireless Communication. That organization has changes it's name to Institute for Communication Research. I was a Senior Member of Technical Staff, and also a Manager for a brief period. I worked with both the Harris Semiconductor as a design engineer, and with Cadence Design System as a Senior Member of Technical Staff. I have designed circuit in both Bicmos and Cmos processes. The geometry ranges from 1.4um to 0.18um. And the operating voltage range from 12v to 1v. I used to lead a team of engineers in the development of high speed analog to digital convertor and the Trancondictance-Capacitor, gm-C, filter for the communication system IF application. I am now a scientist, program manager, IC designer, marketeer, and entertainer.
Although I am still designing circuit in transistor level, my prefered role is system architect. It is very import for the system architect to understand various issues in the IC design, otherwise, a sub-system may not be able to implement.
Looking forward, I enjoy being a pseudo-IC design engineer. Although I can work alone to complete a project of significant proportion, it will probably take too long to develop and the window of opportunity may be missed.
Here are some of the products which were either wholly or partly designed by me while I worked for Harris Semiconductor. The company has been renamed to Intersil .
- HA7210 This is a low power oscillator chip. It requires only the external quartz crystal. It can operate from 10kHz to 20MHz with a proper range selection, and the operating voltage ranges from 2.7v to 5V depending of the operating frequency.
- HI5702 This is the first pipe-lined analog to digital comvertor. I was involved in the sample ans hold amplifier design.
- HMP8112 , HMP8112A, and HMP8115 These are the video decoder chips of different favous. I designed the analog front end.
It is interesting to know how many of these chips are still selling in the marketplace.
My employment with the Cadence Design System was a short one, less than a year. I architected and design the Row/Column driver including the calibration loops for the finger print sensor.
While I was with the Centre for Wireless Communication, I developed a 8bit 80Msps ADC and a 12bit 80Msps ADC in 0.35mm CMOS technology. I also developed a channel selection gm-C filter in 0.8mm SiGe Bicmos technology. All these IP's were intented for the software radio and 1EEE802.11a application. I have given a seminar on the data converter design.
