A co-design study of reconfigurable OSC and dual-band filter

In this paper,the co-design of the reconfigurable OSC and the dual-band filter is studied.After the co-design with the dual - band filter,the phase noises of the oscillator at an offset frequency of 1 MHz at two frequencies improve from -109.1 dBc/Hz and -112.9 dBc/Hz to -125.6 dBc/Hz and -127.9 dBc/Hz,and the 2nd harmonic suppression improve from the -25 dB and -10dB to -44 dB and -55 dB respectively,which improve the OSC's phase noise and harmonic rejection clearly.
