Gate-all-around key to 5nm SRAM cell

A process flow for six-transistor (6T) SRAM suitable for 5nm chips has been created by Belgian research lab Imec working with Unisantis Electronics Singapore. It uses surrounding gate transistors (SGTs) – a vertical gate-all-around architecture developed at Unisantis – to squeeze the cell into foot prints between 0.0184 and 0.0205μm2. “Studies show that the vertical gate-all-around SGT-based ...

40mOhm silicon carbide transistor switches 1,200V and 50A

New Jersey-based UnitedSiC has introduced a silicon carbide transistor that can switch 1.2kV and 47A at 100degC. Unusually for SIC transistors, the gate is fully compatible with existing IGBT drivers, and has a 5V gate threshold – avoiding accidental turn-on issues associated with the lower thresholds of SiC mosfets. Called UJ3C120040K3S, its gate characteristics come ...

Modified Bluetooth could localise to 30cm

A software-only change to the Bluetooth specification could add distance measuring with 30cm accuracy, according to Belgian research lab Imec. Needing only a standard Bluetooth transciever at each end of the link – so applicable to existing phones – adoption could lead to improved positioning, localisation and security. “Today’s localisation solutions merely use signal strength ...

EMI-optimised automotive PoL dc-dc buck

Maxim is claiming “industry’s lowest EMI performance for automotive infotainment and ADAS applications” for a pair of buck converters intended to produce 0.5-3.8V from 2.7-6V. There are two devices, the MAX20073 which outputs up to 2A and the MAX20074 which has a 3A output. Pin-compatible ASIL variants are available. The company also claims “ultra-low quiescent ...

Neural network accelerators for Lattice FPGAs

Lattice has introduced two hardware artificial intelligence algorithm accelerators for its FPGAs, one for binarised neural networks (BNNs) and one for convolutional neural networks (CNNs). Both are aimed at implement neural networks in consumer and industrial network-edge products. They are not suitable for network training, which must be done elsewhere. ‘Binarized neural network (BNN) accelerator’ supports ...

Phased array chip forms beams at 8-16GHz

Analog Devices is aiming at X-band and Ku-band phased-array antennas with an active analogue beam-forming chip that includes four channels of transmit and receive gain and phase control, plus a transmit/receive switch for each channel. The chip, called ADAR1000, operates in half-duplex: In receive (Rx) mode the four Rx inputs are combined to a common RF_IO pin ...
