Abstract

A set of functions and multifunctions has been developed using 0.25 um HEMT and 0.15 um pseudomorphic HEMT processes for automotive radar application at 77 GHz. The main objective of this work was to appreciate which performances can be reached on these processes for high volume applications. A large number of functions were considered in order to be able to fullfil several radar block diagram requirements (FMCW, pulsed, homodyne, heterodyne...). A set of high performance functions has been realised for frequency generation, transmission and reception circuits.
