William J. Pratt Assistant Professor ·
Research and
teach in the field of analog and radio frequency (RF) integrate circuit
design for high speed communication systems. ·
Analysis of
interactions between communication signals and nonlinear circuits. Developed autocorrelation and
statistical analysis techniques for studying the distortion power spectrum
generated by signals applied to behavioral models of nonlinear circuits. ·
Teaching ECE711
Analog Electronics and ECE792X Integrated Circuits for Wireless
Communications (Graduate special topics course). Qualcomm Inc.,
Staff RFIC Design Engineer and Manager ·
Line manager
responsible for supervising four design engineers. Conducted biannual
performance reviews. ·
Lead
design/project engineer for a SiGe BiCMOS direct conversion dual band
transmitter RFIC for AMPS, CDMA, PCS, and WCDMA applications. The design includes direct conversion
upconverter, RF VGA, CELL and PCS band driver amplifiers, TX PLL, TX VCO, and
RX PLL. Developed and evaluated
direct conversion transmitter architecture in three different silicon
technologies. Oversaw a team of
five design engineers. Designed
and modeled integrated copper spiral inductors. Participated in test plan development
and test board designs. ·
Designed a dual
band quadrature local oscillator buffer as part of an image rejection
upconverter mixer using a BiCMOS technology. Provided engineering support for
transitioning the chip into production.
Designed PCB test boards, matching networks, assisted with die probing
for failure analysis, and developed measurement techniques for characterizing
the RF performance of the part.
This design is in high volume production with over 85 million devices
delivered to customers. ·
Designed an 830
MHz stepped gain driver amplifier integrated circuit for driving cellular
FM/CDMA handset power amplifiers using a GaAs MESFET technology. ·
Assisted in the
design and development of a GaAs MESFET broadband upconverter integrated
circuit for use in cellular and PCS dualband CDMA handsets. This chip design was used in over 10
million CDMA phones. ·
Designed
integrated spiral inductors and transformers in a BiCMOS technology. Ericsson Inc.,
Intern Electrical Engineer ·
Researched
active inductor and Q enhancement circuits for use in integrated microwave
filters. ·
Characterized
and tested components for use in cellular telephone designs. Alcatel Network Systems, Intern Electrical Engineer ·
Designed a
broadband optical receiver to convert an optical cable television signal to
an electrical signal suitable for driving a cable distribution network. ·
Designed a
buffer amplifier and a filter circuit for use in a fiber optic communication
system. Millidyne Inc., Raleigh, N.C., 1987-1991. RF Electronic Technician II ·
Assisted in the
development of VHF and UHF pager receivers. ·
