Integrated Circuits

We offer the design and realisation of application-specific integrated circuits (ASICs) in CMOS, BiCMOS and SOI technologies. Many years of experience and profound ASIC development know-how are our foundation to find the best solutions for your application. Together with you we acquire a development concept leading to the perfected compromise between performance, operating conditions and manufacturing costs.

For the design of an integrated circuit we balance the limitations of accuracy and bandwidth, power consumption, chip size and the choice of technology as an example. Such a concept is then implemented according to our qualified ASIC design flow. Thanks to a close collaboration between our design and test engineers as well as with our manufacturing partners, we achieve well-performing ASICs with our first runs (first-time right silicon).

Our team consists of specialists for

  • analog circuit design,
  • digital circuit design,
  • mixed-signal verification,
  • opto electronics and
  • radio frequency technology.

  • Specification development,
  • Circuit design and verification,
  • Layout and test development,
  • Wafer processing,
  • Characterisation and test,
  • Qualification and transition to manufacture.

We document all phases intensively and organize regular project reviews with our customers. We employ certified partnersfor all process steps that we cannot operate in-house, e.g. manufacturing and dicing of wafers, or wire bonding and packaging of the ASICs.

  • System modeling and simulation
  • FPGA and virtual prototyping
  • Analog, digital and mixed-signal design

  • high-temperature (HT) circuits upto 300 °C,
  • control loops,
  • clocked circuits,
  • integrated optical receivers,
  • integrated sensors,
  • digital interfaces,
  • complex sequence controllers,
  • embedded microcontrollers,
  • firmware and driver software.

  • Operational and instrumentation amplifiers (op-amp),

  • low-noise and power amplifiers (LNA, PA), mixers and filters,
  • current and voltage regulators (LDO) and converters (DCDC),
  • delta-sigma modulators (DSM) and phase-locked loops (PLL),
  • bandgap, power-on-reset- (POR) and delay circuits,
  • integrated photodiodes as well as temperature and pH sensors,

  • actor and bus drivers
  • and other components.

We chose the appropriate design methodology

Being a Lead Institution for Analog Mixed-Signal Design Methodology in the Cadence Academic Network, we are familiar with the newest design methods and tools. For the implementation of a mixed-signal ASIC for instance, we use classical techniques based on Verilog-AMS as well as modern approaches for modelling and synthesis based on high abstraction levels with SystemC. Depending on the application, we always evaluate individually if your objectives are achievable with established or innovation practices.

We use the following design tools:

We are familiar with the latest Cadence design software. Our specially developed design environment software manages the design data as well as the setup of the design tools and controls the users’ access privileges.
