Wireless Connectivity Solutions : DRP™ Technology

clear gif

TI's DRP™ technology is a direct response to the dilemma wireless handset manufacturers confront: attracting new users by delivering compelling functionality to all market segments while...fulfilling user demand for less expensive, more power-efficient, smaller and lighter wireless mobile devices.

DRP Technology

How does it work?

DRP technology achieves these seemingly opposite objectives by aggressively integrating handset electronics. TI is applying its digital expertise to the RF analog content of wireless handsets (which often account for up to 40% of the total board real estate). This includes the development of:

  • sampled-data processing techniques
  • digital phase locked-loops
  • switched-capacitor filters
  • oversampling converters
  • digital signal processors
that can assume the functions previously performed by analog amplifiers, filters and mixers.

Instead of a simple (and inefficient) transference of analog blocks into digital technology, DRP technology oversamples analog signals and processes them in the digital domain. The benefits of digital CMOS and deep submicron fabrication are captured.

What are the benefits?

As digital components achieve faster process switching speeds, handset designers can decrease the analog content of their designs. The oversampling rate of analog input signals can be increased, which reduces noise aliasing problems. The design of input networks can be relaxed.

For handset manufacturers, DRP technology delivers many benefits including:

  • Migrating RF processing from the analog to the digital domain enables higher levels of integration in wireless handsets
    • Increased system performance
  • Highly integrated single-die RF and baseband processors reduce design complexity, size, power consumption and cost while enabling greater functionality
    • Smaller bill of materials
    • Smaller form factor to enable small, sleek mobile devices
    • Longer battery life
  • DRP Technology continues to leverage advances in digital CMOS fabrication to smaller submicron process nodes
  • Increased digital content simplifies testing procedures and increases manufacturing yields
