Digital alternative suitable for low power analogue devices
Keith Taylor, Vice President of Licensing and Acquisitions, InventionShare, has announced that InventionShare is now looking for licensing partners to license Circuit Seed circuit designs as an alternative to traditional low power analogue devices. Mr. Taylor said that traditional analogue devices can be made to function at very low power levels, however, there are many short comings with these devices as these circuits are complicated and difficult to design and manufacture.
They require a large area with matched pairs and current mirrors while they use very large transistors. They will generally not work on the small sub 40nm ICs where analogue IC process extensions do not exist or there is sufficient voltage swings available with power supplies in the sub 1V range. Mr. Taylor added that most circuits are also slow, susceptible to parametric changes and higher noise impacting accuracy, yield and performance.
They generally have insufficient dynamic analogue signal swings and operate much slower than digital devices they are associated with. These analogue circuits are designed for specific narrow purposes and manufacturers of these devices often need a large product family due to the limited performance and frequency ranges. Mr. Taylor explained that in contrast, Circuit Seed circuits will operate down to less than 0.1V using a 100% digital process.
The circuit designs are much simpler and do not require matched pairs or current mirrors and will function on 40nm and smaller ICs. The overall circuits are also extremely insensitive to parametric changes making precision designs without precision parts a reality.
These circuits also run at logic speed, are self-biasing and are not subject to parametric changes. They generally work over a very large frequency range, sensitivity and accuracy reducing the number of designs necessary by supporting a wide range of applications.
Mr. Taylor said: “We have a game changer with Circuit Seed, Instead of designing low power analogue circuits that barely work in a very limited range, you could be using Circuit Seed, a simpler design with fewer limitations, better performance, higher stability and greater dynamic range that will reduce the time and cost to design, test, manufacture and support low power circuits.”
InventionShare is now looking for companies that are currently using traditional analogue design processes and looking to for a better design, lower cost process for analogue circuits.
