A 8GHz PLL for FMCW radar using 180-nm CMOS is presented in this paper. Utilizing a fractional-N synthesizer as the FMCW generator, it modulates the frequency across a range of 90 MHz. The phase noise of the proposed PLL is measured of-86.53 dBc/Hz at 1 MHz offset and-123 dBc/Hz at 10 MHz offset. The reference spur is-60 dBc. The dc power consumption is 32 mW under a 1.8-V supply.
