This chapter presents the detailed design and analysis of a CMOS short-range automotive pulse–radar receiver (RX) front-end operating in the UWB band from 22 to 29 GHz. Various design techniques are introduced in order to boost circuit performance at frequencies around only half of the transit (or unity current-gain) frequency, fT, of the transistor (f T ≈ 55 GHz for 0.18 µm CMOS). An interference-reduction scheme is also presented that allows efficient use of the allocated power-constrained spectrum, while minimizing the interference with other systems operating in the same frequency range. Circuit techniques used in the UWB RX front-end design enable the radar sensor to potentially achieve a high range resolution and detect objects at a close range, thereby demonstrating suitability for integration in short-range radar systems.
