Seamless was formed by Professor Peter Kinget and former student Jayanth Kuppambatti to apply developments in switched-mode analog signal processing across a broad range of applications and making use of nanoscale manufacturing processes.


Seamless Devices is a semiconductor IP company, following a similar business model to ARM Holdings Ltd., and is owned by Allied Minds plc. Allied Minds is private equity-funded incubation company that forms, funds, manages and builds startups based on early-stage technology developed at US universities and laboratories.

Seamless Design’s switched-mode operational amplifier (SMOA) can address high frequency signals using leading-edge transistors and therefore is a candidate technology for adding analog circuits for SoCs.

The company claims that its first set of AFEs make it easier for architects of signal processing systems to address the trade-off between performance quality and power usage in electronic devices.  

The company is introducing a portfolio of products, including analog-to-digital converters (ADCs), analog filters, and a programmable gain amplifier. 

"These products demonstrate our SMOA’s potential to enable a new class of performance," said Roger Yang, general manager of Seamless Devices, and a vice president at Allied Minds. "SMOA is not just built for wireless connectivity; there are a host of potential applications in healthcare, the military, and more."

The company’s ADCs offer 80MHz bandwidth from 0.9V operation, automatic background PVT calibration and available in 28nm CMOS processes.

Further technical specifications are only available on application.
