Designed, migrated and optimized an industry current sense IC in mass production from one
process to a new process. The design was based on opto-coupler including LED driver, photo diode
trans-impedance amplifier, sigma-delta modulator, low-pass filter, band gap reference, etc.
Performed product measurement, evaluated the key performance and collected – more... the measurement
data. Provided test plan for mass production, analyzed mass production test data and suggested
corresponding possible cause for yield reduction if there were any problem. – less
