Abstract :
A 65 nm CMOS LO generation system capable of providing quadrature signals over the wide 2 to 16GHz frequency range for short-range radar applications is presented. Made of a 6.5 to 18.4GHz PLL, and an injection-locked programmable divider by 1, 2, or 4, it features a phase noise at 10MHz offset <; -129 dBc/Hz, a RMS jitter <; 0.68 ps, a reference spur level <; -48 dBc, and a settling time of 2 μs.
