Abstract
- A differential ring CMOS voltage-controlled oscillator (VCO) with dual-delay path topology is proposed in this paper. In this work, the focus area is to improve the tuning range of VCO and phase noise performance of the VCO. The dual-delay path topology is used with P-MOS as load in series with negative-skewed delay transistors. This design gives the wider tuning range and this increases the phase noise performance of the VCO. After the post-layout simulation, frequency tuning range and power dissipation range are 730 MHz to 2.81 GHz and from 1.32 mW to 4.62 mW respectively. The phase noise for this VCO is −97.35 dBc/Hz at 1 MHz offset. The technology used in this work was taken from the library of SCL 180 nm technology. This design exhibits excellent phase noise performance. [ABSTRACT FROM AUTHOR]
