Platforms for Semiconductor Design

Reuseable functions across processing platforms & mixed signal systems.

Intrinsix Platforms and semiconductor IP provide unique solutions that can be quickly brought to bear on customer projects.  The two most direct and tangible benefits are in speeding time to market and predictability of schedule and outcome.  This, in turn, drives down effective cost of development and, of course, accelerates time to revenue for Intrinsix customers. 

Intrinsix platforms consist of groups of semiconductor IP which have been pre-configured for a particular market or purpose.    Often, the Design IP (whether represented by RTL or transistors in a particular process) is paired with Verification IP to create a development suite for that market.   A critical aspect of the Intrinsix IP strategy is that we avoid marketing our IP as standalone products.  This strategy frees us from typical “Not Invented Here” attitudes and positions our solutions as agnostic in regards to IP choices.    Our customer’s view of Best-in-Class price/performance wins the day.   Every day.   With this approach, we are able to partner with all providers of IP, such as EDA companies and boutique IP companies.    New solutions and options appear all of the time and Intrinsix strategy ensures a level playing field for our customers and their choices.

Most of the Platforms and IP offered has been derived from focused internal R&D, funded solely by Intrinsix.   But a significant portion also comes directly from Intrinsix participation in the Small Business Innovate Research (SBIR) program. This program funds companies to create compelling solutions for government and commercial advancement.    Check out our SBIR and Patents page for a complete list.

PWM Regulator IP

Pulse-width modulation (PWM) is a modulation process or technique used in most communication systems for encoding the amplitude of a signal right into a pulse width or duration of another signal, usually a carrier signal, for transmission. Although PWM is also used in communications, its main purpose is actually to control the power that is supplied to various types of electrical devices, most especially for inertial loads such as AC/DC motors.

Intrinsix has developed a number of PWM IP components that are highly reusable for new PWM designs.  This will reduce engineering time and improve reliability through the reuse of proven designs.

Sigma-Delta Refinery

Sigma-Delta Modulation Explained

Use of a Sigma-Delta Modulation scheme in the design of Digital-to-Analog Converters (DACs) and Analog-to-Digital Converters (ADCs) allows for very efficient and/or high performance data converters.  Sigma-Delta Modulation (aka SD Modulation, SDM or Delta-Sigma Modulation) is not a new technique, but has been deployed relatively recently in a wide range of  applications thanks to continued advances in CMOS semiconductor technology.  Intrinsix has developed several families of Sigma-Delta based IP blocks that are designed to be inserted into larger designed targeted for standard CMOS processes such as those available from TSMC, UMC, SMIC. Chartered and others.

Intrinsix Sigma-Delta Modulator Refinery

Designing a finely tuned SDM-based device, such as a data converter, can be a very time consuming effort, even by engineers very familiar with the technology.  This is where Intrinsix can get you ahead of the curve.  Intrinsix has developed the Intrinsix SDM Refinery, a proprietary design automation suite.  When deployed by our Mixed Signal Design Team, SDM Refinery allows us to quickly produce optimized Sigma-Delta Modulators (SDMs) and SDM-based, over-sampled DACs and ADCs.   Not only do the results come faster, but the components developed with the SDM Refinery are optimized far beyond what could be expected from a manual design methodology. 

 

Some of the additional features of the refinery:

  • Highly Automated
  • Custom ADC/DAC IP
  • Optimized to System Needs
  • Several Patents
