Holst Centre, imec and ROHM Semiconductor Co. Ltd. announced that they have entered into a strategic partnership for research collaboration on ultra-low power (ULP) radio technology for small battery-operated wireless devices. In current short-range radios, the Power Amplifier typically uses around 50% of the total power consumption of the system, while the Phase-Locked Loop (PLL) is responsible for another 30%-40% of the power consumption. While a low power PA can contribute to the low powe...
