A Low-Power CMOS Wind Sensor

This work describes a low-power and low-cost alternative to mechanical wind sensors, suitable for volume production in standard CMOS processes. The CMOS wind sensor operates in the electro-thermal domain; therefore, it has no moving parts and therefore requires very little maintenance. Moreover, the CMOS wind sensor is an active sensor, compared...

Integrated Readout Circuit for Cross-Correlation Based Ultrasonic Ranging

Distance measurement using ultrasonic waves is employed in a wide range of industrial applications. In this thesis our main goal is to investigate the possibility of processing ultrasonic signals with a ??-modulator and to process its bitstream output signal with the cross-correlation technique, while being independent of the transducer that is...
