degisn & prdoucts Anaglo degisn Startup launches switch-mode op amps, ADCs Seamless Devices Inc. (San Jose, Calif.), a startup spun out of Columbia University, New York, in 2014 has introduced its first products, a set of analog front-end circuits for use in LTE, WiFi and microwave applications. 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 earlystage 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. The company’s ADCs offer 80MHz bandwidth from 0.9V operation, automatic background PVT calibration and available in 28nm CMOS processes. Seamless Devices Inc. www.seamlessdevices.com. Former games company offers analog IC for IoT Aplix IP Holdings Corp. (Tokyo, Japan), a public company that previously made games software and video animation, has re-invented itself as an Internet of Things company with the introduction of an analog interface IC for the smart home. Aplix claims that this analog IC can be used to connect a variety of home and office appliances, such as thermostats, water detectors, heaters and motors, to the Internet. Aplix is also developing relevant digital logic and plans to supply its analog and digital circuitry in the form of intellectual property. A single-chip IoT solution (SoC) can be realized by combining Aplix IP with Bluetooth semiconductor IP and processor IP. Aplix said it plans to license its analog and digital design IP library to semiconductor companies and foundries. BiCMOS 44pin QFN or 64pin QFP 0.5mm pitch that provides 3V power regulation; 8 or 16 channel comparator input; an 8 or 16 channel voltage level shifter; 4 channel LED driver and 4 channel analog switch, according to the company’s website. But it appears to be part of a long-term plan to license the makings for a IoT interface ICs. The company has published a roadmap that extends to 2018. Aplix IP Holdings Corp. www.aplix-ip.com Kandou SerDes capable of 1Tbit/s The Glasswing SerDes core in development at startup Kandou Bus SA has been tested and demonstrated the “capability of achieving” 1Tbit/s chip-to-chip at less than 1W of power consumed. Kandou’s technology is based on signaling method called Chord Signaling in which correlated signals are sent across multiple wires. The version of Chord Signaling employed in Glasswing, CNRZ-5 coding, delivers 5 bits over 6 wires for a total bandwidth of 125Gbps. The link achieves a BER of <10^-15 at the targeted data rate of 25GBaud and can support channels up to 12mm in length (die-to- die insertion loss up to 6dB) at full rate and 24mm at half rate. The link has also proven to be robust under stress including overclocking up to 30GBaud, temperature testing from 0° to 100°C, and running full rate up to 24mm. Measured power for a single instantiation of the link is 1.1pJ/bit and in a quad configuration would drop to 0.97pJ/bit. Through the use of a bi-directional version of Glass wing 2Tbps of bandwidth can be achieved using only 320 signal pins and standard bump pitches, the company said. The Glasswing link IP is delivered as a hard IP and licensed customers receive: data sheet and application notes, channel compliance guidelines, standard integration views (GDS, LEF, verilog, .lib), production test support, Spice models and Kandou proprietary KEYE and TAU modelling tools. Kandou Bus SA www.kandou.com DACs with NVM retain settings in power-off The low-power, 8-/10-/12-bit, single and dual-channel MCP- 48FXBXX digital/analogue converters with SPI have optional integrated EEPROM to reduce microcontroller overhead: shutdown modes reduce current consumption for power-critical applications. The six-member MCP- 48FEBXX DAC family offers integrated EEPROM to save DAC settings at power-down, while the MCP- 48FVBXX family provides lower-cost alternatives for applications that do not require integrated memory. These low-power, single and dualchannel DACs feature 8-, 10- and 12-bit resolution, a Serial Peripheral Interface (SPI), and are available in 10-pin MSOP packages. Examples of their wide range of applications in the consumer, industrial, automotive and other markets, includes set-point/offset trimming, sensor calibration, instrumentation, and motor control. The integrated EEPROM option enables DAC settings to be restored at powerup and reduces microcontroller overhead, while the various shutdown modes significantly reduce the device current consumption for power-critical applications. These devices feature low Differential Nonlinearity (DNL) error to sustain monotonic output and low Integral Nonlinearity (INL) error for better linearity. They can operate in extended-temperature conditions. Microchip www.microchip.com 40 Electronic Engineering Times Europe January 2016 www.electronics-eetimes.com
