Analog Design Engineer

Overview

Conduct design and development of image sensor technologies, focusing on transistor-level design of analog and mixed-signal circuits for CMOS Image Sensors, including  array, column-amplifier, comparator, ramp generator, ASRAM and XDEC using Cadence Virtuoso. Contribute to whole chip floorplan design and pad frame; perform analog and mixed-signal circuit layout design using Cadence Virtuoso (e.g., ). Collaborate with layout engineers on full-chip layout integration and improvement, also using Cadence Virtuoso.

Perform sub-block and entire image sensor readout circuit simulations with Analog FastSPICE (AFS), Empyrean ALPS, and Nano Spice. Conduct design verification (DRC, LVS, PERC) with Siemens Calibre; perform whole-chip IR drop checks with Ansys Totem. Modify scripts using Perl; collaborate with Digital Engineers to define and design the analog-to-digital interface. Work with verification, process, test, and application engineers to debug, characterize, and optimize the performance of fabricated image sensors.

Analyze project-specific specifications (speed, linearity, noise, power consumption, etc.) and improve circuit designs or implement innovative solutions to meet performance requirements. Define corners based on chip operating conditions to ensure reliable operation with sufficient margin across conditions. Propose innovative and creative solutions, including new circuit R&D, to stay ahead of current technology.
