The increase of consumer electronics and communications
applications using Radio Frequency (RF) and microwave circuits has
implications for oscillator design. Applications working at higher
frequencies and using novel technologies have led to a demand for
more robust circuits with higher performance and functionality, but
decreased costs, size and power consumption. As a result, there is
also a need for more efficient oscillators.
This book presents up to date information on all aspects of
oscillator design, enabling a selection of the best oscillator
topologies with optimized noise reduction and electrical
performance. RF and Microwave Transistor Oscillator Design
covers:
* analyses of non-linear circuit design methods including
spectral-domain analysis, time-domain analysis and the quasilinear
method;
* information on noise in oscillators including chapters on
varactor and oscillator frequency tuning, CMOS voltage-controlled
oscillators and wideband voltage-controlled oscillators;
* information on the stability of oscillations, with discussions
on the stability of multi-resonant circuits and the phase plane
method;
* optimized design and circuit techniques, beginning with the
empirical and analytic design approaches, moving on to the
high-efficiency design technique;
* general operation and design principles of oscillators,
including a section on the historical aspects of oscillator
configurations.
A valuable reference for practising RF and Microwave designers
and engineers, RF and Microwave Transistor Oscillator Design
is also useful for lecturers, advanced students and research and
design (R&D) personnel.
