A low-power total power radiometer for passive imaging applications is presented. The radiometer is manufactured in a 130 nm SiGe technology with an ft/fmax of 250/370 GHz. The radiometer achieves a minimum noise equivalent temperature difference (NETD) of 0.21 K at 155 GHz. By optimization of the building blocks and biasing stages, a low-power system with a total power consumption of 64 mW is achieved. Due to its low NEP and low-power consumption, the system enables further integration into high-density sensor arrays for passive radiometry in the D-Band.
