Our Solutions

  • New neurostim ASSP

    The CSI021 application specific integrated circuit features 4 independent 8-bit linear DAC programmable current sink/source outputs with up to 6mA full-scale sink, and 1.5mA full-scale source currents.

  • New neurostim eval board

    Evaluation board for CSI021 aimed at possible neurostimulation / neuromodulation applications.

  • Custom ASICs Solutions

    We offer complete custom IC solutions optimized to meet the specific size, power, and functional requirements of your application.
    • Implantable drug delivery integrated circuits
    • Implantable peripheral nerve stimulator integrated circuits
    • Stereo class D audio driver 2.2 watts (4 ohm)
    • Ingestible medical sensor integrated circuit
    • Battery Backup integrated circuit
    • And many more
  • We were tasked by a medical device company to reduce power consumption in their design. We provided the turn-key IC that increased the time between battery charging from less than 2 days to almost 1 month (over 16x improvement).
  • Decades of experience in low power medical integrated circuit design has allowed us to develop ultra-low power medical ASICs. Reducing the system power and size has enabled devices to be implanted at or near the site of therapy, thereby simplifying implantation and reducing the need for long leads.
  • Using advanced analog IC design techniques and by leveraging our library of low power circuit IP, we have produced integrated circuit designs with 10 times or more improvement in battery life from the prior generation of products.
  • Today’s electronics often require multiple voltage domains. We routinely convert raw battery voltages into higher voltages for analog front-end circuits or lower voltage for digital supplies. Efficient voltage conversion and controlling the enabling of circuits has allowed us to reduce power and enable lower capacity batteries, thus reducing overall system size.
