Abstract
A bolometer type ultra-sensitive silicon sensor pixel of a multi-pixel sensor wherein each pixel includes a detector stage, an intermediate stage, and a heat bath stage. The detector stage, the intermediate stage and a portion of the heat bath stage are generally co-planar and are interconnected by I-beam bridges so as to permit mutually co-planar rotation in response to stress and strain. Electrical coupling is improved between a micro-antenna and the detector stage by a two stage transformer assembly that couples the micro-antenna to the detector stage.
Claims15
A bolometer type thermal radiation sensor pixel of a multi-pixel sensor, comprising:
- an antenna for receiving incident electromagnetic radiation;
- a detector stage, a heat bath stage, and an intermediate stage located between the detector stage and the heat bath stage;
- and
- a multi-stage transformer assembly coupling thermal radiation received by the antenna to the detector stage.
