Many have predicted the eventual phasing out analog circuitry in favor of newer digital technologies. However, a lot of products depend on this critical technology to interface to real world stimuli such as wireless transceivers, optical, chemical and temperature sensors. VREF Innovations recogizes that analog design is not a dying art and that the need to incorporate analog fucntionality into most products is greater than ever. We have extensive experience designing precision complex analog circuits and subsystems such as:

• Sensor Interfaces (Optical, Temperature etc....)
• Power Management  and Power Supervisory Circuits
• Data Aquisition Systems (A/D Conversion, D/A Conversion)
• Voltage References
• Drivers (LED, Laser)
  
• Current Sources
• Voltage Regulators
• DC-DC  and AC-DC Switching Power Converters (Buck, Boost, Flyback)
• Amplifiers
• Filters
• Oscillators
• Operational Amplifier and Comparator Circuits
• Communications Interface
• Precision Circuits
• Low Noise Circuits

Using mathematical modeling tools such as Mathcad, we also perform the analysis essential to analog circuit design such as:

• Worst Case
• RSS (root-sum-sqaures)
  
• Noise
• Tolerance Stackup / Error
• Component Stress
  

By combining analog circuits with other technologies we offer complete product solutions to our customers.
