Vita
Urs Hecht received the B.Sc. and the M.Sc. of electrical engineering in 2016 and 2018, respectively, from the Technische Universität Berlin.
During his studies he concentrated on analogue circuit design. Highlights were the design of a Ultra-Low-Power CMOS Temperature Sensor (Bachelor’s Thesis), a two-stage telescopic OTA and a 150 MS/s 1.5 Bit 11 ENOB Pipeline ADC Stage in 28 nm CMOS.
His Master’s Thesis “56 GBaud PAM-4 CMOS Transmitter Architectures” concentrated on finding the optimal transmitter equalization architecture to push the boundaries of VCSEL-based optical communication systems beyond the current state of the art.
In 2018, he was awarded the Friedrich-Wilhelm Gundlach-Preis by the "Verein der Freunde der Hochfrequenztechnik an der TU Berlin e.V." for the reasurch during the period of his Master's Thesis.
He joined the chair of mixed-signal circuit design in May 2018.
