This past October, the FCC began to explore opening up 1,200 megahertz of spectrum in the 6 GHz band for different types of unlicensed uses. This band is currently populated by microwave services that are used to support utilities, public safety, and wireless backhaul. Studies show that sharing this band with unlicensed operations is feasible—and can put massive amounts of new spectrum into the hands of consumers. Unlicensed innovator Claus Hetting of WI-FI NOW said, “This is without a doubt the single biggest opportunity in Wi-Fi—and probably in wireless—in a generation.” He added, “This 6 GHz spectrum boost will launch the Wi-Fi industry into a new growth trajectory.” Circuit Seed is aiming to have the best of both worlds: protect today’s incumbent users of the band while turbocharging the Wi-Fi networks and applications of the future. While this is good news for Wi-Fi, it will not work without adequate filtering to split this super wide frequency allocation into sub-bands. Ceramic filters will be able to do that, but it will be static. If an enterprise or a home wants smart frequency allocation with some ‘AI’ behind it, dynamic low loss filtering is a must. Circuit Seed’s 100% digital process for analog signal processing is an ideal solution for high performance filtering with low noise and low signal loss.

In March of 2018, Transparency Market Research published a report announcing that the worldwide low noise amplifier market is estimated to be worth US$ 7.9B by 2026. The LNA industry is fragmented with the usual group of semiconductor companies. Circuit Seed is a new platform utilising the Complementary Current injection Field Effect Transistor (CiFET) for processing analog signals using 100% digital components. This allows you to build a low noise amplifier using only two CiFETs which can be perfectly tuned to a 50 or 100 ohm antenna by adjusting the i-ratio. The power consumption is a fraction of traditional LNA devices, with a lower noise floor resulting in better range and lower SNR. The small size, less complexity and fewer BOM lowers the cost of the device. Circuit Seed is an ideal solution for low power LNAs.

Planet Analog featured, on 25 May 2019, Bill Schweber’s article “What to do about analog inaccuracies?”. Three options were presented: calibrate the sensor; use better parts; if possible, self cancellation. Circuit Seed is a new platform utilising the Complementary Current injection Field Effect Transistor (CiFET) for processing analog signals using 100% digital components that can be constructed to build any low power analog device. Circuit Seed designs are aligned with all three options presented in the article. Circuit Seed is completely linear, and insensitive to temperature and process variation without correction circuitry that reduce inaccuracies. The build blocks are better parts with low power consumption and low SNR ratio. The CiFET itself uses self cancellation due to the complementary nature of the circuit improving performance. Finally, the designs are less complex thereby requiring less wafer space, fewer BOM which means less cost. In a recent contribution to Planet Analog, author and engineer Bill Schweber takes a look at the importance of being accurate and even tries to and out just how close is ‘close enough’ when it comes to analog design.
