Quadrature vco thesis

Sirable characteristic for example, quadrature lo signals are required in most modern digital communication systems, while conventional vco's usually generate differential sig- nals thus there is usually a quadrature generation circuit in current radios, which consists of a pair of divide-by-2 digital dividers or poly-phase. This thesis discusses low-power wireline receivers with particular focus on clocking circuitry and architectures these clocking solutions bandwidth when used to provide large phase shifts by selectively injecting different phases of a quadrature-lc or ring vco, this problem is obviated resulting in reduced phase noise.
