چکیده
|
This paper proposes a novel wideband lc-based voltage-controlled oscillator (vco) for multistandard transceivers. the proposed vco has a core lc-vco and a tuning-range extension circuit,which consists of switches,a mixer,dividers,and variable gain combiners with a spurious rejection technique. the experimental results exhibit 0.98 to 6.6ghz continuous frequency tuning with -206dbc/hz of fomt,which is fabricated by using a 0.18m cmos process. the frequency tuning range (ftr) is 149,and the chip area is 800m 540m. © 2011 yusaku ito et al.
