Norm’s resume.
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.
