摘      要：The wideband CMOS voltage-controlled oscillator（VCO）with low phase noise and low power consumption is presented for a DRM/DAB（digital radio mondiale and digital audio broadcasting）frequency *** order to obtain a wide band and a large tuning range,a parallel switched capacitor bank is added in the LC *** proposed VCO is implemented in SMIC 0.18-μm RF CMOS technology and the chip area is 750 μm×560 μm,including the test buffer circuit and the *** results show that the tuning range is 44.6%;i.e.,the frequency turning range is from 2.27 to 3.57 *** measured phase noise is-122.22 dBc/Hz at a 1 MHz offset from the *** maximum power consumption of the core part is 6.16 mW at a 1.8 V power supply.
