Panagiotis Dimtsoudis

I’m Panos, an electrical engineering student at Penn, originally from Greece. I design circuits at the transistor level in Cadence, build and debug analog boards, and characterize ferroelectric junctions from 14 to 400 K on probe stations.

B.S.E. and M.S.E., Electrical Engineering, University of Pennsylvania · expected May 2028

Availability Looking for Summer 2027 internships in IC design, analog hardware, and device characterization.

    Complete

    The core operation of a neural-network accelerator, a multiply-accumulate fed by two custom SRAMs, designed from the 6T bitcell up in Cadence Virtuoso.

    • Analog PCB
    • ESE 3190
    • 2026
    • Solo
    Complete

    Two MOSFET LC oscillators beat against each other, and metal near the search coil shifts the tone. I took it from schematic to a fabricated two-layer board, soldered it by hand, and brought it up stage by stage.

    Complete

    A Guitar Hero controller rebuilt as a playable synthesizer on an ATmega328PB: bare-metal C, PWM audio with a decay envelope, whammy vibrato read through the ADC, and an I2C LCD for remapping fret notes.

    • What brokeThe board reset whenever the speaker drew current. A 12 V pack and two 5 V regulators fixed it.

    Teaching Assistant

    ESE 2180: Electronic, Photonic, and Electromechanical Devices, Penn Engineering

    I write homework, lab worksheets, and exam problems for an 80+ student device physics course. I set up and teach hands-on labs that connect device physics to measurement, hold weekly office hours on transistors, LEDs, and photovoltaics, and grade with written technical feedback.

    Undergraduate Research Assistant

    Device Research and Engineering Laboratory, Penn Engineering

    I characterize 6 nm AlN/AlScN/AlN ferroelectric junctions from 14 to 400 K on cryogenic and high-temperature probe stations: DC and AC J–V, C–V, PUND pulse tests, breakdown, and endurance. I write the Python that extracts device parameters and compares switching, retention, and endurance across devices and temperature.

    I contributed measurements and analysis to a manuscript in preparation on cryogenic all-nitride ferroelectric memory, and built 3D CAD models of the device stack and of an 8 × 8 crossbar array for compute-in-memory work.
