Abstract
The design and performance analysis are presented for a passive uncooled radiometer pixel suitable for integration in 28 nm CMOS technology. In the configuration a single wideband antenna, operating from 200 GHz to 600 GHz, is connected to a pn-junction diode. Including the antenna-detector impedance mismatch, the detector shows an average NEP of 2.71 pW/√Hz such that, together with the antenna, the radiometer promises fully passive and uncooled imaging capabilities with 2.6 K temperature sensitivity at a 10 Hz refresh rate. The design is planned for fabrication and measurement.
