ZigBee chip to speed time to market
1 min read
Dublin based Duolog Technologies has taped out a 0.13µm IEEE802.15.4/Zigbee radio test chip as part of its 802.15.4 transceiver development program.
Ray Bulger, Duolog’s ceo, said: “This tape out is a significant step for Duolog along the value added line as a fabless semiconductor house and accelerates our path to the complete 802.15.4 SoC.”
The transceiver offers a low data rate solution with multi year battery life and low complexity. The radio has been designed with a top down approach and includes novel features and architectures. According to Jason Drew, the company’s radio development manager, the radio has been designed to be best in class in terms of power and current consumption.
Duolog has also developed an optimised hardware centric 802.15.4 MAC and baseband designs to ensure an ultra low power transceiver. This hardware intensive solution offers an optimal power and cost balance, ensuring that the system maintains flexibility while minimising silicon area.
Designed at Duolog’s analogue/rf ic design centre in Hungary, the chip also features a power management block on the silicon, along with an LDO, battery monitor and bias current generators.
