Work History

Years Employer Title Department Responsibilities
Years: 2015 to Present Employer: Undisclosed Title: Principal Analog Design Engineer Department: MCU32 Responsibilities: Expert was responsible for the concept and design of a variety of low-power CMOS analog and mixed-signal circuits for consumer electronics, using 180 nm, 90 nm and 55 nm technologies. Examples of designed circuits include operational amplifiers, bandgap reference circuits and oscillators.

Among other achievements and significant activities, he:
• Redesigned previous designed circuits to improve performance or fixed observed problems in silicon
• Ported several circuits from one technology process to another (combinations of TSMC, Global Foundry, ATMEL) and, at the same time, made design improvements
• Worked with integration engineers on floorplanning and routing and placement of circuits on chips
• Supervised the layout of designed circuits and, sometimes, made my own layout modifications to reduce/verify extracted simulation results
• Worked with fab team to make sure FIBs were done accordingly to specifications
• Worked in the lab with test engineers to validate circuits and find root causes of failures
Years: 2011 to 2015 Employer: SeaVision Inc. Title: Senior Analog Design Engineer Department: AZ Design Center Responsibilities: Expert was responsible for the concept and design of low-power CMOS analog and mixed-signal circuits for imaging applications, such as Digital Still Cameras and Cellular Phone Camera Modules, using 90 nm and 55 nm technologies, all from scratch. During this time, he:
• Worked with Business Manager to design, chip integration, verification and tapeout of imaging chips and several building blocks to support these chips, such as precision voltage and current reference generators, programmable and fixed-gain amplifiers, comparators, level-shifters, LDOs, PoR, UVLO, temperature monitor, and ramp generators
• Laid out and/or supervised/coached the layout of designed circuits
• Supervised and coordinated project progress to assure compliance and completion on schedule
• Drove root-cause analysis, debugging, characterization and correction of issues observed on chip's first prototypes
Years: 2009 to 2011 Employer: Analog IC Design Engineer Title: Analog IC Design Engineer Department: Independent Consultant Responsibilities: Expert designed several analog circuits for audio, imaging and power supply applications, in 0.35 µm, 0.18 µm and 0.13 µm technologies. In this role, he:
• Designed programmable gain amplifiers, a programmable voltage reference generator and a programmable,  multi-outputs current reference generator
• Identified improvements that were implemented in existing blocks of image sensor analog circuits, buck voltage regulators and start-up sequencer. The improvements reduced power consumption, layout area and, in some instances, simplified the logic circuits.
Years: 2007 to 2011 Employer: Maxim Integrated Prod. Title: Member of Technical Staff Department: Responsibilities: He researched and designed CMOS circuits for low power and power management applications. During this time, Expert:
• Served as lead designer for the MAX8831 chip
◦ Redesigned several existing blocks based on customer requirements to improve performance
◦ Monitored work progress and helped completion of project on schedule
◦ Drove root-cause analysis and correction of issues observed on device's first run
◦ Performed IC bench evaluation, debugging, characterization, correlation, and launching into large volume production
◦ Worked with Business Managers to adapt/change circuits according to new customers' needs, opening new business opportunities for the reuse of chips, saving design time and costs.
• Joined project of MAX8694 and
◦ Redesigned 2 LDOs to conform to  new customer specifications
◦ Drove root-cause analysis and correction of issues observed on silicon evaluation of previous version
◦ Performed bench evaluation, debugging, characterization, correlation, and helped to launch into large volume production
◦ Contributions to other products: design of a temperature monitor, design of a programmable gain amplifier, design of a programmable current generator
• Conducted root-cause analysis of several chips and drove modifications and improvements to correct problems.
Years: 2007 to 2007 Employer: IC Power Title: Senior Analog Design Engineer Department: Responsibilities: Expert designed CMOS analog circuits for audio applications. In this role, he:
• Designed three programmable gain amplifiers, for audio applications, each with different performance specifications
• Supervised layout and extraction of designed circuits
Years: 2004 to 2007 Employer: IC Media Corp. / Magnachip Semiconductors. Co. Title: Senior Analog Design Engineer Department: AZ Design Center Responsibilities: Expert researched and designed CMOS analog circuits for imaging applications, in UMC's 0.35 µm and 0.25 µm technologies, MagnaChip's 0.18 µm and 0.13 µm technologies. In this role, he served as lead analog designer responsible for the design, simulation, layout supervision and chip integration of the analog chain processing, for several imaging chips. He also assumed complete ownership of the analog chain processing of several image sensor chips, working with BM and AE to design the best solutions to customers in a feasible time and within budgets.
Years: 1999 to 2003 Employer: Motorola, Inc. Title: Senior Staff Engineer Department: ImageMos Sensors Responsibilities: In this role, Expert was responsible for research, development, design, layout and characterization of low-power CMOS analog and mixed-signal electronic circuits for imaging applications. He was also responsible for the design, simulation and layout supervision of analog circuit blocks (miscellaneous op amps, switched-capacitor circuits, and voltage/current reference generators) in the analog processing chain used in several Motorola imaging chips.
