Job Title: Analog Design Engineer
Job Duties:
Conduct design and development of image sensor technologies, work on transistor level design of analog and mixed-signal circuits for CMOS Image Sensor such as asic_pixel array, column-amplifier, switch capacitor, comparator, ramp generator, ASRAM and XDEC by using Cadence Virtuoso. Work on whole chip floorplan design and pad frame. Work on analog and mixed signal circuits layout design by Cadence Virtuoso, such as column_array. Collaborate with layout engineer on whole chip layout integration and improvement by Cadence Virtuoso. Perform sub-blocks and whole image sensor readout circuit simulation by simulators such as Analog FastSPICE (AFS), Empyrean ALPS and NanoSpice. Perform design verification such as DRC, LVS, PERC check by using Siemens Caliber. Collaborate with Digital Engineer to define and design the analog to digital interface. Collaborate with verification, process, test, and application engineers to debug, characterize and optimize performance of fabricated image sensors. Propose innovative and creative solutions along with new circuit R&D and be ahead of current technology. Process the column readout data from the CMOS sensor using data processing software like Excel and MATLAB. Perform a performance check and conduct debug analysis based on the data results. Design the internal Discrete-time Circuits, Peripheral circuits and Timing control for a CMOS image sensor, including bias circuits, driver/level shifter, switched capacitor, logic gates and slew rate control.
Requirements:
