ASIC DESIGN ON MEDICAL DEVICES

1.MEMS Driver ASIC for Contact Lens Sensor:

We have designed and developed an ASIC for sensing to set up straight with the contact lens.

The MEMS sensor which can be digitized through ASIC is reading and transfers the assessments back to the recorder with the same RF link used to power the device using load modulation techniques.

By using a 0.35µm process, Faststream could incorporate power capture and conditioning, RF signaling, high linearity ADC, and digital control functionality on a single die within the limited power budget and at low cost.

 

Benefit for the customer

Faststream Technologies regulates the whole ASIC life cycle for Sensimed, comprises of design, prototyping, industrialization, and supply chain for different volume production. The bumped die is attached directly onto copper traces within the lens during manufacture, connecting it to the antenna and MEMS array.

Using these processes Faststream could sense the demand for a high ENOB process during keeping within the power resources of the coil antenna.

2.ASIC BASED MEDICAL IMAGING READOUT SYSTEM:

The prototyping board depending on ASIC is designed to readout Analog and Digital ASIC. This platform is designed for imaging purposes: Calorimetry, Silicon Tracker, Medical Imaging.

The platform provides up to 240 digital high-speed I/O and 8, 120 MSPS 14 bit ADC channels. Almost all modern front-end ASIC can be validated with this system It is possible to read-out:

  • Pre-amplifier/shaper only ASIC with dedicated Analog output for each channel.
  • Multiplexed channels Analog Output ASIC.
  • Digital-only ASIC, for example, ASIC with the only comparator inside designed for applications requiring only timing information.
  • ASIC with integrated ADC and/or TDC.
  • 70 PS resolution TDC on Petiroc ASIC.

 

Faststream Technologies carried out all Virtual Blocks to:

  • Executed trapezoidal filter or charge integration to measure the energy of the pulses.
