An analog or mixed-signal circuit design position on a high-caliber
team providing complete solutions to customer problems.
An individual-contributor position focusing on system, block and/or
transistor level design is preferred.

Experience Summary:

Proven architect, ability to balance between analog and digital
partitions, and tradeoffs between CDR and equalization.
Team leader, design experience at system, block, transistor levels.
Best in-class record of fully functional first silicon over 20+ years
Published papers and patents spanning many areas of IC design.
Experienced in design and layout issues for deep submicron CMOS design.

Experience Details:

April 2012 – Present – Cisco Inc. Allentown
Team Leader, Analog CMOS circuit design

Nov 2010 – April 2012 – Lightwire, Inc Allentown, PA.
Senior Analog/MS Design Engineer

Architecture and transistor level design of BBCDRs for 10 Gb/s and
28 Gb/s NRZ data rates. Circuits done include LC tank oscillator,
D/A converters, A/D (nA to uA range) converters, sense-amp latches,
20 GHz DLL using mixers. Oversaw layout teams, helped less
experienced engineers, wrote Skill code to improve productivity,
and completed design review and design specifications documentation.

May 2005 – Oct 2010 : LSI/Agere Systems; Allentown PA.
Principle Engineer – LSI; DMTS – Agere Systems

Storage PHY Design Group.
Architected, and designed the CDR for the Shanghai family of PHYs.
Novel bang-bang phase detector and digital loop filter clock
and data recovery architecture, for data rates ranging from
1.06Gb/s FC up to 8.5 Gb/s FC. Developed novel digital phase
detector and analog circuit structures to allow the CDR to be
self-trimming with no additional test circuitry for improved jitter
tolerance performance. CDRs are described by a major customer as
the best they have seen, and as world class by all major customers.

Designed main latch core and array for each product. Designed each
major analog block in the CDR over the course of several years,
improving state of the art and design methodology along the way.
Extensive use of Ocean scripts to make simulation self testing to
allow regressions. Involved in debugging many major issues accross
the product line, including transmitter, CMU, and Rx issues.
Developed core adaptive equalization algorithms. Circuits designed
or improved include core latch, matched multi-phase GHz clock
generation and distribution, analog reference voltages. re-designed
LC tank core oscillator for one product. The CDR was fully
functional in all mask-orders, allowing for system level prove in,
and device evaluation.

Team leader. Experienced in taking a product from blank paper concept
through volume ramp. Experienced in leading technical teams up 20
people, covering analog and digital design, layout, validation,
verification, and documentation. Experienced in working with
management to provide reasonable schedule estimates, and assigning
work loads based on talent and needs of the business. Experienced in
business risk assesment. No desire to manage people.

Worked on the central, roaming, and spread spectrum interpolators.
Introduced gray coding to remove clock glitches and improve performance.
Worked through many layout and floorplan issues.

May 2002 – September 2004 : Agere Systems, Allentown, PA.
Distinguished Member of Technical Staff; Analog Design Groups

High-Speed SERDES design. Responsibilities included CDR architecture
definition and simulation, transistor-level design, silicon debug,
layout oversight, and working with other design and support
organizations to resolve customer-related issues in a time-sensitive

Designed the core Clock and Data Recovery PLL for a 1-4.25 GB/s NRZ.
This included development of a phase-based simulink model for
simulating closed-loop performance of the non-linear bang-bang PLL in
reasonable simulation times. Determined all CDR small-signal and block
level requirements. Completed transistor level circuit design of
oscillator and matched phase buffers, charge pump, pfd,
OTA (dual loop pll), and filter components. Initial silicon was
fully-functional. Lead debug and re-design effort to identify root-cause
and fix parametric shortcomings.

Designed a frequency synthesizer in TSMC’s 90nm technology.
Circuits designed included oscillator, pfd, charge pump, OTA, and
filter components.

Summer 2001-May 2002: Acting Technical Manager
Agere Systems, Allentown, PA.

Responsible for a circuit design and test program development team
working on multiple projects, including voice band codecs, and
AFE’s for digital telephone and IP phone products.
Left the job by choice after realizing the job is not for me.

January 1988 -August 2001: Agere Systems, Lucent Technologies,
AT&T Bell Laboratories
Member of Technical Staff; Distinguished Member of Technical Staff

Designed a 256MHz to 1.2 GHz low-noise frequency synthesizer
Designed low noise 30dB preamp.
Designed a 70.656 MHz 50 ppm 3rd overtone crystal oscillator.
Designed multiple PLLs of 622 MHz (16 matched phases).
Designed a T1/E1 frequency synthesizer.
Lead Design Engineer 100BaseT4 Ethernet Transceiver.
Designed first fully-integrated Ethernet 10BaseT transceiver.
