A Low-Power Thermal Wind Sensor in CMOS Technology

Wind sensors are widely used in many critical applications, such as navigation, weather forecast, aerospace and wind energy assessment. The thermal wind sensor can measure wind speed and direction at the same time, by measuring the temperature gradient on the sensor’s surface which is induced by the wind flow. Compared to traditional mechanical...

Highly linear LNA design for base station applications

As the first stage of the amplifier chain aiming for the base station applications, a highly linear low noise amplifier (LNA) dictates very high performance for optimum coverage with a best signal quality. In today’s commercial market, the GaAs enhancement-mode pHEMT based LNA is dominant. However, a SiGe-based LNA, due to its high integration,...
