Abstract
There is provided a high responsivity device for thermal sensing in a Terahertz (THz) radiation detector. A load impedance connected to an antenna heats up due to the incident THz radiation received by the antenna. The heat generated by the load impedance is sensed by a thermal sensor such as a transistor. To increase the responsivity of the sense device without increasing the thermal mass, the device is located underneath a straight portion of an antenna arm. The transistor runs substantially the entire length of the antenna arm alleviating the problem caused by placing large devices on the side of the antenna and the resulting large additional thermal mass that must be heated. This boosts the responsivity of the pixel while retaining an acceptable level of noise and demanding a dramatically smaller increase in the thermal time constant.
