A capacitive pressure sensor with CMOS switched-capacitor circuitry for on-chip signal conditioning is introduced. It features differential generation and treatment of pressure-induced capacitance...
Brockherde, W., Hosticka, B.J., Manoli, Y., Mokwa, W.
Recent developements in silicon technology allow the implementation of nonelectrical functions and CMOS-electronics on the same silicon substrate. Thus microsensors and microactuators can be merged...
OASE. A knowledge based environment for analog circuit design (1990)
Brockherde, W., Hess, G., Hoffmann, K., Klinke, R., Krohm, F., Mertens, M., ...
A novel knowledge based environment for analog circuit design is presented. It features a hierarchical design style, multifunctionality, and fully embedded standard tools. The prototype...
CMOS analog front-end for ripple-control receivers (1990)
Rainer, E., Brockherde, W., Hosticka, B.J., Münster, I.
A microcontroller-compatible analog front-end for ripple-control receivers is described. It serves to demodulate ripple-control signals transmitted by public electrical utilities over 50 Hz power...
The art of analog circuit design in a digital VLSI world (1990)
Brockherde, W., Hosticka, B.J.
This contribution surveys issues and challenges of analog design in VLSI. Since today's VLSI is still largely digital, the analog design plays a rather peripheral role. Due to an increasing tendenca...
Ein flexibles Ohrprothesen-System (1989)
Bollerott, M., Brockherde, W., Kellings, G., Scherer, K.
Cochlea-Implantate (CI) oder Ohrprothesen ersetzen bei tauben Menschen in gewissem Umfang die Funktion des defekten biologischen Systems Außenohr, Trommelfell, Hörknöchel und Hörschnecke...
Sprachdatenreduzierung und -codierung bei einer elektronischen Hörprothese (1988)
Bollerott, M., Brockherde, W., Kellings, G., Scherer, K.
Design criteria of a monolithic front-end for a microstrip vertex detector are discussed. Two basic items are considered, a preamplifier combining junction field-effect transistor and complementary...

Dieser Beitrag befasst sich mit dem Entwurf von analogen MOS-Schaltungen, wobei vor allem die Realisierungen in der CMOS-Technologie beruecksichtigt werden. Zunaechst werden die...
Entwurf und Optimierung von Schalter-Kondensator Noise-Shaping-Codern bis zum Grad 4 (1986)
Brockherde, W., Büddefeld, J., Hosticka, B.J., Lamkemeyer, M., Richert, P.
Eine verallgemeinerte Struktur eines Noise-Shaping-Coders wird untersucht. Sie erlaubt den Entwurf und die Analyse von A/D-Umsetzern bis zum Grad 4. Die Koeffizienten der Coder verschiedenen Grades...
CAD tools for the design and analysis of switched-capacitor networks (1986)
Brockherde, W., Büddefeld, J., Hosticka, B.J., Richert, P., Zimmer, G.
We present CAD tools for the design and analysis of switched-capacitor networks, both linear and nonlinear. The switched-capacitor networks implemented in MOS and CMOS technologies are of primary...
