Senior analog designer with 12 years experience of designing various analog circuits, with recent focus on designing different types of regulators to generate optimum supply voltages or back bias for VLSI to operate with minimum power consumption. These circuits are: DC/DC switching regulator for Dynamic Voltage Scaling application LDO linear regulator High efficiency, low ripple, programmable negative charge pump (Imax=10mA@-1V) Programmable output Class AB amplifier that performs analog summation or subtraction Temperature sensor with bandgap reference and SAR ADC Digital and analog sensors that monitor process corners or chip conditions Also designed or supervised the development of analog and digital IP blocks for microprocessor and North Bridge that includes: Programmable PLL/DLL Video DAC High speed I/O Low power mega cells such as FIFO, register file, CAM, TLB, datapath, etc. With experience in both analog and low power VLSI design, always served as bridge between R&D and implementation group as to what’s ideal and what’s feasible. Helped shorten decision making process in early phase of the project. Being an analog guy myself, am also very familiar with different power reduction and management techniques for digital circuits. As one of the few founding members of LR2 team, helped grow the group from ground up and eventually led to more than $50M revenue in licensing and service. Being in a service and licensing group, Interacted with different customers. This is a very rare experience for most design engineers and from the process really I learned a lot of things like people skills, marketing, program management, contract drafting and execution, networking, etc. As they said in the commercial, this is something money can’t buy. With my ethnic background, I also have very good connections with many OEMs/ODMs in Asia. read more ...
