JOB OBJECTIVE

Analog or mixed-signal integrated circuit design

WORK EXPERIENCE

Sigmatel Incorporated - Analog Design

 April 2000- Present
Designed high-swing, high-linearity, low-power integrated 5V SHDSL line driver; designed high-swing, high-linearity, low-power 1.8v headphone driver; designed very small high-speed, current-steered D/A; and designed general op-amps. Two patents issued- two more filed. Part-time CAD support.

Motorola - Wireline Analog Design

 July 1998- April 2000
Migrated ADSL analog front end to 0.25u CMOS.  Redesigned bandgap reference, attenuator, VCXO, clock doubler, and sigma-delta OTA.  Made significant improvements in performance, design for manufacturability, area, and power.
 

Motorola - Engineering Rotation Program

 July 1997- July 1998
Wireless Mixed-Signal Design Completed substrate noise analysis of codec design. Article published in Nov. 1999 IEEE Circuits and Systems II:  "Analysis of Ground-Bounce Induced Substrate Noise Coupling …" Consulted on substrate noise reduction strategies for numerous Motorola chip designs.
CAD Tool Development Designed, coded, and supported a new tool for high-level datapath design. Completed Tcl/Tk program in half the expected time period
Wireline Analog Design Migrated ADSL sigma-delta OTAs to new fab technology.  Built sigma-delta C simulation to verify gain and bandwidth specifications for OTAs. Researched and implemented new folded cascode design strategy, reducing power 73%
Failure Analysis Designed and conducted experiment to verify chip substrate noise analysis.  Work resulted in a 3X reduction in PLL jitter on codec chip

SOFTWARE, HARDWARE EXPERIENCE

Operating Systems: UNIX / AIX / HP-UX / Solaris / Linux / Windows
Languages:  C++, shell scripting, Tcl/Tk, Java, little Perl
Design and Analysis: Matlab, MCSPICE, SmartSpice, Mathematica, Cadence & Mentor Graphics (schematic capture and layout), Ptolemy(SPW forerunner)
Hardware: digital oscilloscopes, logic analyzer, spectrum analyzer, Focused Ion Beam, Energy Dispersion Spectroscopy, Scanning Electron Microscope
