Abstract
This paper presents a quadrature voltage controlled oscillator (QVCO) with the delay-locked loop (DLL) for ultra wideband (UWB) application. A new architecture of delay-locked loop is presented to achieve low power consumption and low-noise operation. A system analysis of delay locked loop based QVCO is discussed including the transfer function and the stability. Also, this DLL architecture is implemented in a 40-nm CMOS technology. From the simulated result, this design achieves 40% delay range from 6-9 GHz, with -149.1 dBc/Hz phase noise at 100 MHz frequency offset. The power consumption is 11 mW, and the phase accuracy is less than 5°.
