Circuit Seed is a breakthrough technology company created by InventionShare that has designed and extensively patented a new semiconductor structure called the Complementary Current-Injection Field-Effect Transistor (CiFET™).

The CiFET™ Technology

This  transistor architecture can accept current or voltage in and produce current or voltage out. Early developments demonstrate unparalleled linearity, significantly lower noise and greater amplification for analog circuits such as those used in electronic sensor applications. Virtually any analog circuit can be constructed using CiFETs such as TIAs, LNAs, ADCs, VCOs, synthesizers and PLLs.

CiFETs operate over an extremely wide operating temperature (beyond AEC-Q100 Grade 0) and can run on standard scalable CMOS. The CiFET shows high noise immunity and for the first time, has opened the door to having analog and digital building blocks running side-by-side on the same chip in the same process node.

Low Power Consumption

Often 80%+ less, smaller battery or extended battery life

Low Thermal Budget​

Low power consumption generates less heat, reducing the need for shielding and heat sinks​

Wide Temperature Range​​

80%+ plus circuits are insensitive to temperature which eliminates the need for correction circuitry

No Changes to Manufacturing Process​​

100% CMOS digital components and workflow with existing tools

Linear Performance​​​

Without correction circuitry – further reducing complexity, power consumption, size, development and cost

Tuneable Device​

Allows a change in the ratio of the width/length of the source and drain channel of the CiFET for different performance requirements, reducing complexity

Wide Bandwidth​​

Supports more applications and allows more flexibility for filtering

Small Size and Less Complexity​

Simplifies development and testing, reducing the requirement for senior analog designers

Scalable​​

Will work in all IC nodes including < 28nm

Less Cost​​​

NRE, development, testing, wafer size, higher yields, fewer BOM, higher reliability
