Expert in Embedded Computing, Computer Architecture, Systems on Chip (SoC) and Low Power Electronics
Expert ID: 730852 Texas, USA
Expert also worked for Intel, Infotronics and other divisions of Cirrus Logic where he did system design, computer hardware and extended his doctoral research of low power computer arithmetic designing digital multiplier for multiple applications. This work required extensive digital circuit simulations at the unit level and chip top level.
Expert has extensive experience in circuit design following his interest in this area from his master's degree at Stanford where his depth area was circuit design and VLSI. He created the architecture and designed a SRAM compiler for seismic applications which was implemented and used at Cirrus Logic for several generations. He also designed Read Only Memory (ROM) devices, digital multipliers and DC-DC converters for multiple applications.
In addition to his experience in full custom memory design, Expert has designed several flash (EEPROM) interfaces for smart sensors and other applications like smart meters and RFID.
Expert has dedicated most of his career to perform work in mixed-signal integrated circuits for several applications. Expert worked for many years at Cirrus Logic as an engineer and later on as a Design manager at the industrial product division. He led the architecture of smart sensors and the implementation of analog/digital for applications like weight scales, seismic applications and digital signal processors. Systems were modeled in C language and implemented in Verilog HDL. This work resulted in product lines which produced more than $100 million in revenue.
Expert served as VP engineering for RFMicron where he used his mixed signal background and his extensive experience in digital systems to define and implement the architecture for a new generation of RFID devices.
Expert has extensive experience in multiple areas of intellectual property. He is an inventor with 22 issued and 2 pending patents. As a design manager at Cirrus Logic and VP of engineering at RFMicron he supervised patent submissions and negotiated intellectual property contracts.
Expert has performed asset valuation analyzing hundreds of patents for multiple customers. He also worked in patent infringement developing claim charts, patent searchers and reverse engineering analysis.
Expert developed a smart sensor platform for Cirrus Logic. The platform was an ARM7 micro controller based integrating key peripherals: a high performance A/D converter, digital filter, embedded flash memory, RAM, ROM and several communication peripherals.
Expert has worked most of his career for mixed signal companies where engineers are responsible on both design and verification of the different IP blocks and also share the responsibility for verification at the system level. He has also worked as part of verification teams writing verification plans. During the last 5 years Expert has applied in his projects some of the latest verification trends: Common Power Format (CPF), Assertions, Random vector generation and Mixed Signal Simulation.
Expert has worked on energy efficiency evaluation from his doctoral studies and throughout his career in multiple projects. It still continues to be a main topic of interest.
