Samenvatting
In this paper, a quadrature voltage controlled oscillator(QVCO) is presented with delay-locked loop for ultra wideband
application. In this work, a new architecture of delay-looked
loop based QVCO is applied to achieve low power consumption
and ultra-wideband operation. In this paper, a system analysis
of delay locked loop based QVCO architecture is discussed
including the transfer function and the stability. Also, this QVCO
architecture is implemented by a 40nm CMOS technology. From
the simulated result shows, this design achieves delay range
from 6-9 GHz, with -148 dBc/Hz phase noise at 100 MHz offset
frequency. The power consumption is 11 mW, and the phase
accuracy is less then 5°.
