Overall presentation

The Institute for Electrical Measurements and Circuit Design (Institut für Elektrische Mess- und Schaltungstechnik: EMST) of Vienna University of Technology (TUV) specialises in the theory and practice of circuit design, electrical measurement procedures and equipment based on ultrasonic, microwave and optical principles. The knowledge and experience with analog and optoelectronic integrated circuits (OEICs), optical receivers and laser drivers of the circuit design group at EMST ranges back to 1996. Operational amplifiers, comparators and filters in digital 0.12µm and 65nm CMOS were developed up to the GHz range. Numerous OEICs for DVD and optical data communication based on new circuit concepts were demonstrated by EMST up to a data rate of 11Gb/s. An optical burst-mode receiver in 0.12µm CMOS achieved a sensitivity of -28dBm at 1.25Gb/s. Transimpedance amplifiers (TIAs) in 0.35µm SiGe BiCMOS achieved a photocurrent range of 130dB at a bandwidth of 250MHz. A 36-channel receiver OEIC achieved a data rate of 108Gb/s at only 800mW power consumption. Currently in the circuit design group four Ph.D.s and nine Ph.D. students are investigating analogue nanometer CMOS circuits, CMOS and BiCMOS OEICs for various fields of applications with world leading results in four projects funded by industry and by national programs in close cooperation with industry. Besides design software like CADENCE and a net of workstations, equipment for electrical and optical characterisation of ICs and OEICs is installed at EMST. There are signal and digital pattern generators, network and spectrum analysers with bandwidths up to 30GHz and digital sampling oscilloscopes (20GHz) as well as single-shot oscilloscopes (40GS/s), a bit error analyser up to 10Gbit/s and a 200mm waferprober with thermochuck from 20 to 200°C, for instance.

Activities within HELIOS

Inside HELIOS EMST of TU Vienna will design a 10Gbps TIA in SiGe 0.35µm BiCMOS technology, as well as a modulator driver for 10Gbps and also one for 40Gbps produced in IHP 0.25µm SiGe BiCMOS technology.
