Low-Noise Mixing Circuits in CMOS Microwave Integrated Circuits
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, ...
Phase Generation and Manipulation in CMOS Integrated Circuits
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 ...
A 26 GHz Phase-Locked Loop Frequency Multiplier in 0.18-um CMOS
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
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. ...
