By Mike Wens

Technological development within the semiconductor has ended in a revolution in the direction of new complicated, miniaturized, clever, battery-operated and instant digital functions. the mandatory offer voltage(s) of those purposes seldom fits the various battery voltage, as a result of technological purposes. as a result, effective voltage converters are an important to bridge this voltage hole, with out compromising the battery’s autonomy as do linear voltage converters. furthermore, either house and price constraints shape a powerful incentive in the direction of fully-integrated CMOS switched-mode DC-DC converters, successfully putting off the necessity for big and dear off-chip passives (inductors and capacitors).

To do so target Fully-Integrated Inductive DC-DC Converters in usual CMOS presents the subsequent assets:

  • A company yet complete theoretical base on switched-mode DC-DC converters, giving the fashion designer the an important info for knowing the working ideas and primary barriers of other kinds of DC-DC converters, together with linear converters, charge-pump converters and inductive converters.
  • An assessment and comparability of alternative sorts of inductive DC-DC converters and their mutual comparability in the direction of monolithic integration presents a flexible wisdom base to compare witch the limitations of the converter to be designed.
  • An actual and speedy version for fully-integrated inductive DC-DC converters is mentioned, considering all of the major losses in CMOS applied sciences. This version permits very actual prediction of the steady-state parameters, together with the potency. in addition, it permits a quick convergence in the direction of the optimum layout values, regardless of the multi-dimensional design-space.
  • High-speed keep watch over schemes for controlling the output voltage are defined intuitively and from a pragmatic viewpoint. moreover 3 new regulate options: COOT, SCOOT and F²SCOOT are printed. Many concrete schematics are supplied and defined, that are extensively utilized within the a number of chip realizations. As such, this hands-on technique offers the “feeling” for keep watch over method layout for fully-integrated DC-DC converters to the designer.
  • The ebook is concluded with seven sensible proof-of-concept chip realizations of fully-integrated DC-DC converters, thereby utilizing either bondwire and metal-track inductors. Many useful matters, comparable to chip lay-out and dimension setups, are mentioned, supplying the clothier much more to-the-point useful details at the subject.

Fully-Integrated Inductive DC-DC Converters in commonplace CMOS is a vital paintings for study and layout engineers which are faced with totally- and/or highly-integrated DC-DC converters. The technique during this ebook levels from an organization theoretical base to appreciate the trade-offs, in the direction of a hugely functional and real looking attitude.

Modem Theory: An Introduction to Telecommunications

On the middle of any glossy conversation method is the modem, connecting the information resource to the verbal exchange channel. this primary path within the mathematical conception of modem layout introduces the speculation of electronic modulation and coding that underpins the layout of electronic telecommunications structures. a close remedy of center topics is supplied, together with baseband and passband modulation and demodulation, equalization, and series estimation.

RF and Digital Signal Processing for Software-Defined Radio: A Multi-Standard Multi-Mode Approach

Software-defined radio (SDR) is the most popular sector of RF/wireless layout, and this name describes SDR strategies, thought, and layout ideas from the viewpoint of the sign processing (both on transmission and reception) played via a SDR approach. After an introductory assessment of crucial SDR ideas, this ebook examines waveform production, analog sign processing, electronic sign processing, information conversion, phase-locked loops, SDR algorithms, and SDR layout.

Sampling theory and methods

Sampling idea and techniques provides the theoretical features of "Sample Surveys" in a lucid shape for the good thing about either undergraduate and put up graduate scholars of facts. It assumes little or no historical past in likelihood concept. the writer offers intimately a number of sampling schemes, together with basic random sampling, unequal likelihood sampling, and systematic, stratified, cluster, and multistage sampling.
