Experience

1) Design Manager Aug 1998 to Current

Digitlog Technology Inc- San Mateo, CA

Design Analog & Mixed-Signal and Power IC chips including layout and testing for various customers in the bay area and abroad. Typical Design work flow includes top level behavior modeling and simulation with SIMPLIS/SPICE SIMULATOR. After verification of top- level blocks against specifications, IC transistor design begins with Hspice simulations. After design reviews, physical layout starts and tapeout with LVS/DRC clean gds database. Have extensive experience in

• Behavior and transistor simulation

• Mix signal analog and power IC integration

• High Voltage processing(40v BCD, 730v power mosfet integration low voltage CMOS)flow and semiconductor physic

Recent a) System IC Behavior chips modeling, development: dc-dc boost Power supply converter(for Apple’s power supplies RFQ)

b) 2 phase power buck(6Amp,RAD HARD) controller(for Microsemi)
