Multiplexed Twin PLLs for Wide-Band FMCW Chirp Generation in 130-nm BiCMOS

We present a pair of fractional-N phase-locked loops (PLLs) followed by a multiplexer (MUX) integrated in one chip. The PLL outputs are multiplexed during chirp generation to increase the frequency modulated continuous wave (FMCW) signal bandwidth to 5GHz around a 31-GHz center frequency. The phase...
