A 26 GHz Phase-Locked Loop Frequency Multiplier in 0.18-um CMOS
(2009-04-25)
This thesis presents the analysis, design and characterization of an integrated
high-frequency
phase-locked loop (PLL) frequency multiplier. The frequency multiplier is novel
in its use of a low multiplication factor ...
Radio frequency direct-digital QPSK modulators in CMOS technology
(2007-09-28)
In this thesis, novel direct-digital Quadrature Phase Shift Keying (QPSK) modulators are proposed in low-cost Complimentary Metal Oxide Semiconductor (CMOS) technology for radio frequency (RF) wireless applications. ...
Phase Generation and Manipulation in CMOS Integrated Circuits
(2008-04-01)
In this thesis three circuits are presented that demonstrate the creation and manipulation of various phases over a large bandwidth. Many systems demand the interoperability of various circuit blocks over a large frequency ...
Low-Noise Mixing Circuits in CMOS Microwave Integrated Circuits
(2009-08-25)
In this thesis, three low-noise active mixing circuits are presented in CMOS technology. Mixers can be found at the front-end of almost every communication systems. However, despite many advantages the active mixers have, ...
