In this publication an integrated dielectric sensor with read-out circuit in SiGe BiCMOS technology at 125GHz is presented. The sensor consist of a 500 µm shorted half-wave coplanar waveguide transmission line in the top metal layer. Read-out of the sensor is performed by measurement of its reflection coefficient with an integrated multiprobe reflectometer and signal source. The MMIC has been fabricated...
In this publication an integrated reflectometer in SiGe BiCMOS technology for sensor readout at 62 GHz is presented. The circuit includes an oscillator, a six-port reflectometer, and a dummy sensor for verification purposes. The circuit has a bandwidth of 8GHz at a center frequency of 62 GHz. It operates at 3.75V supply voltage and consumes 282 mW. The measurement principle is demonstrated and the...
