A new low phase noise LC-tank CMOS cascode Cross-coupled oscillator
In this paper we introduce a new low phase noise cascode Cross-coupled oscillator by use of the general topology of Cross-coupled oscillator and cascode amplifier. By simulation a comparison between the conventional Cross-coupled oscillator and the new cascode Cross-coupled oscillator is also presented, which shows that the latter improves the phase noise by 2dB under the same conditions. The figure of merit (FOM) of −186.4 dBc/Hz is achieved for the new oscillator by simulation.
