Our Management Team
LEADERSHIP
Fotis Plessas, Ph.D.
Fotis Plessas is an Analog/Mixed Signal and RF Design Engineer. He has worked with the Industrial Systems Institute (ISI/Athena RC), the Institute of Communications and Computer Systems (ICCS/NTUA), Analogies S.A., Theta Microelectronics, HDL-DH, and through subcontracting with larger US and European Firms (Top 5 Automotive Semiconductor Companies).
In 2016 he founded Nanozeta together with the late Mikes Sisois (Atmel’s CIO and Vice President). He was the CTO of the company, leading all the technical activities till 2025. During this period innovative IPs have been developed, among others for ultra-low power Bluetooth and imaging radars for autonomous driving. He is now the managing director of the company.
From 2014 to 2016 he was with HDL-DH, leading a contractor’s team that built several analog IP blocks for a customer in the processors and microcontrollers market. IP included Integer and fractional PLLs, a High-Speed USB PHY, and a Full Speed USB Transceiver. He worked for Theta Microelectronics Inc. from 2013 to 2014, leading a team that built several low jitter fractional-N/integer-N PLL IP blocks for a customer in Bluetooth series product industry.
Between 2006 and 2013, he was with Analogies S.A, as a Senior Engineer and Manager responsible for the development of high-speed wired and wireless connectivity cores for SoC solutions (i.e. a USB3.0 PHY, a DDR2/3 PHY and a 60GHz PLL). For 6 years prior to Analogies, he was involved in several research activities at the Applied Electronics Laboratory and the Industrial Systems Institute working mainly in the area of RF communication circuits and analog and mixed-mode circuit design.
He has extensive experience in wired and wireless communication systems engineering. He is a senior member of IEEE, and IEEE MTT/CAS/SSC societies. He holds a Ph.D. in Electrical Engineering and an MBA. His professional experience includes 25 years in Engineering/Technical Management and 3+ in senior-level management roles.
Vasilis Panagiotopoulos, MEng.
Vasilis Panagiotopoulos is an RF and analog/mixed-signal design engineer with over 15 years of experience, specializing in PLL/VCO and crystal oscillator design, from schematic to layout and verification. He also has extensive experience in low-power PAs, amplifiers, clock distribution, and related circuits.
During his PhD work, he collaborated with Analogies S.A. and Theta Microelectronics on USB 3.0 PHY design and 60 GHz PLLs, where he focused on oscillator development and theoretical noise research.
Since joining Nanozeta Technologies in 2017, he has led and contributed to multiple projects including (further details under NDA):
- VCOs ranging from 2.5 GHz to 20 GHz, across high-performance and ultra-low-power designs, in technologies from legacy CMOS to RFSOI and down to 5 nm FinFET.
- PLLs and crystal oscillators, delivering circuits that consistently meet specifications on first silicon
- Analog and mixed-signal subsystems, where he has applied his expertise in both design and verification
As a team leader, Vasilis is a natural problem-solver with strong top-level knowledge spanning both analog and digital domains. He has led the design and verification of complex AMS systems and full chips, as well as extensive post-silicon debugging and lab validation to ensure designs perform as intended.
