- Abstract
- In this paper, we present a new concurrent dual-band VCO with single resonator. The proposed oscillator is a new concurrent dual-band VCO, which does generate two bands of carrier frequencies simultaneously. One band is generated from 5.1 GHz to 5.5 GHz, and the other is from 8.5 GHz to 9.1 GHz. Low phase noises at 100 kHz offset are measured as - 111 dBc/Hz from 8.86 GHz and -114 dBc/Hz from 5.132 GHz, respectively. The concurrent dual-band VCO consumes a core current of 4 mA at 4.0 V The VCO has been fabricated using 0.8μm SiGe BiCMOS process.. © 2007 IEEE.
