Skillsets:
ü
General board-level
circuit design, with an emphasis on proper grounding and shielding,
proper power distribution, design for manufacturability and test. Component
selection and specification to meet performance benchmarks. Bill of Materials
management, cost estimates, interface with layout engineering and contract
manufacturing. OrCad schematic capture, Linear Technology power supply
simulation
ü
Precision analog
design, specializing in high precision and accuracy to 18
bits, both integrating and successive approximation A/D converters
ü
Signal conditioning
for low level signals and sensors, especially
industrial signals such as thermocouples, RTD’s, bridges, pressure sensors,
etc. Linearization, cold junction compensation, lead resistance compensation,
using both linear and digital (microcontroller-based) techniques
ü
Embedded 8 bit
microcontroller experience, especially
variants of the 8051 architecture, using very tight assembly language coding.
Extensive experience over nearly 30 years with this family of microcontrollers.
Procedural and mathematical code, including single precision floating point.
Also, some experience with the Microchip PIC family, and currently reviewing
the MSP430 family
ü
Communications
experience: RS232, RS485, using asynchronous protocols.
I2C/SMBus and SPI peripheral communications. Experience with Bluetooth at the
system/module level
ü
Windows GUI
programming, using Embarcadero Delphi XE. Applications
programs, Demo programs, and utility programs written to support testing, or as
companion programs in systems
ü
Ultra low power
design for battery-based products and small systems, using
micropower components, small switching power supplies, Li-MgO coin cells
ü What I DON’T do: To avoid wasting anyone’s time, these are the things that I am not
experienced in doing: VHDL, Verilog, C/C++programming, high power, RF, TCP/IP,
or Visual Studio.
