This paper presents the design of an ultra-low-power LC quadrature VCO (QVCO). It is designed in a single-poly seven-metal 65-nm CMOS process. Several aspects of state-of-the-art QVCO design are addressed, for example tank design and circuit topologies ...
In this work, a new differential topology of Colpitts VCO with an enhanced transconductance is presented. The proposed circuit is consisted of an NMOS and a PMOS differential Colpitts cores configured as complementary, and also an LC resonator. The VCO ...
This paper presents a low power and low phase noise CMOS integer-N frequency synthesizer based on the charge-pump Phase Locked Loop (PLL) topology. The frequency synthesizer can be used for IEEE 802.16 unlicensed band of WiMAX (World Interoperability ...
