A multi-band single-loop PLL frequency synthesizer with dynamically-controlled switched tuning VCO Conference Paper uri icon


  • A phase-locked loop (PLL) frequency synthesizer architecture for multiple-band applications is presented. A dynamically-controlled switched tuning voltage-controlled oscillator (VCO) is used to achieve superior frequency range and phase noise performance over a conventional PLL. Implemented in 1.2 CMOS, the PLL has a 111-290MHz range, phase noise of -92.3dBc/Hz at a 50kHz offset, and dissipates 9mW from a 2.7V supply.
