Analog can’t touch Digital

I just want to send out a sincere “Thank you” to those of you who have repeatedly inquired about our SigmaVision® IC. We especially want to thank those who have supported us with your time, your guidance, and in some cases your money.    We are not yet ready to launch but we are getting lots of questions so we want to share a small piece of our enthusiasm.

While device manufacturers are spending millions to squeeze an extra 2-3dB of signal-to-noise (SNR) from their systems, our digital approach to capacitive sensing is jumping far ahead to SNR levels never before imagined. Current analog and mixed signal sensing technologies using a switched capacitive approach simply cannot operate well in a world that requires flexibility, changing features, adaptability, dynamic programmability, low power and ultra-high sensitivity in noisy environments. We are confident our digital approach is a game changer for capacitive sensing (and for a number of other sensing technologies).

Digital is Coming to Sensing:

The “Digital Revolution” is marching forward, transforming every industry it touches.  Digitization was the key enabler for “Computers” and later for “Smart Phones”.  Digitization had a profound impact on the audio world (e.g. music) leading to market changes that could not have been conceived when capture, storage and reproduction were analog based. These changes shifted corporate valuations of winners and losers to the tune of billions of dollars.  “Sensing” technology has NOT fully benefited from the digital revolution, because far too many analog components still remain. Full digitization of “sensing” will be a key enabler for the next wave of “Interactive Machines”.  Much like digitization of audio led to a revolution in the music industry, the digitization of “sensing” will have significant impact in our target markets.

Sensing finally going digital enables machines in so many new and different ways. Simplified digital sensing including analog-to-digital and digital-to-analog is important because it expands interaction for our machines, sensing presence, temperature, fluids, pressure, movement, force, and more. We first think of sensing touch on displays but this is just our starting point for this technology. Capacitive sensing at our level of performance enables a number of new uses with the availability of much more information.   “User experience” is judged by the quality of our interaction with machines.  Our SigmaVision® technology moves sensing from the realm of mixed signal or analog silicon into full digital logic making profound changes in how hardware is designed, impacting potentially billions of devices in the process. More importantly, this shift improves the sensitivity and clarity of how machines will sense the world around them.  Better information leads to better decisions which produces better results.   Interactions will improve as limitations on sensing are removed. We look forward to watching how the digitization of “sensing” will remove current barriers and transform products in ways that we haven’t even imagined.
