Summary

Lead Inventors: Yannis Tsividis, Ph.D.

Problem or Unmet Need:
In any signal processing circuit, the input amplifier and the output amplifier change gain simultaneously when an input signal changes intensity; this inherently causes some output distortion. Previous solutions to minimize distortion, such as the floating point technique and generalized floating point technique, are sensitive to parasitics and not suitable for CMOS technology.


This technology provides several solutions on how to implement filters with reduced power dissipation requirements which reduces filter noise. It also reduces response time and causes no output distortion. This technology has wide use in any signal processing applications.

Potential Applications

  • Signal processing in digital wireless communications, broadband access, digital audio, and high-resolution imaging
  • Health and medical care devices such as monitoring and checking devices

Advantages

  • Signal processing circuits are on standby mode, which consume less power, reduce the response time and speed up the switching time
  • The circuit does not interrupt output or cause distortion
  • Suitable for CMOS technology
