Abstract :
A fully-integrated, low-power 1830 MHz voltage-controlled oscillator (VCO) used in the frequency synthesizer of an implantable wireless multisensor microsystem (IWSM) dedicated to in vivo monitoring of biological parameters is presented. The VCO, implemented in a 90-nm CMOS process, draws 380 muA from a 1-V supply. Post-layout simulations show that the amplitude of oscillations is 450 m V, the phase-noise is -120 dBc/Hz at 1 MHz offset from the carrier and the frequency tuning range is 100 MHz.
