A 90nm CMOS SoC UWB pulse radar for respiratory rate monitoring

UWB technology (3.1 to 10.6GHz) allows new applications for both data communication and sensing. Due to their potential in terms of resolution and extremely low level of EIRP spectral density (<; -41.3dBm/MHz), UWB radars are very attractive for a large set of civil and military sensing applications, as ground penetrating, surveillance, localization, intra-wall and through-wall detections and biomedical imaging. Moreover, with respect to continuous-wave (CW) radars, UWB radar transceivers present a lower circuit complexity since no frequency conversions are required, leading to lower power consumption (Pc) for longer battery autonomy.
