RF circuit design - theory and applications

The objective of this textbook is to develop the RF circuit design aspects in such a way that the need of transmission line principles is made clear without adopting an electromagnetic field approach.

RF circuit design - Theory and Applications

Therefore, no EM background is necessary beyond a first year undergraduate physics course in fields and waves as provided by most colleges and universities. Students equipped with the knowledge of basic circuit theory and/or an exposure to microelectronics can use this book and cover the entire spectrum from the basic principles of transmission and microstrip lines to the various high-frequency circuit design procedures.

RF Circuit Design - Theory and Applications by R.Ludwig and P.Bretchko

For the advanced students the entry into this field is often pursued through an electromagnetic field approach, while for the technologists the basic circuit aspect embedded in Kirchhoff's laws is the preferred treatment.

Op amps for everyone – Ron Mancini

The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp.

Op amps for everyone: design reference By Ron Mancini

"The op amp is treated as a completed component in this book.The op amp will continue to be a vital component of analog design because it is such a fundamental component. Each generation of electronics equipment integrates more functions on silicon and takes more of the analog circuitry inside the IC.

Op amps for everyone

Don’t fear, as digital applications increase, analog applications also increase because the predominant supply of data and interface applications are in the real world, and the real world is an analog world. Thus, each new generation of electronics equipment creates requirements for new analog circuits; hence, new generations of op amps are required to fulfill these requirements. Analog design, and op amp design, is a fundamental skill that will be required far into the future."

Uninterrupted Power Distribution for Homes

The Enhancement of Mains power system for Homes and Small Business is critical. The population is more now and the use of electricity for more appliances becomes inevitable, this makes power shortages imminent.

Power Electronics & Solar Energy

The power to Homes can be distributed by two types of phase lines (live), a common neutral and the usual earth. High Phase is for Heaters and Motors and some lighting too. This phase can be shut down on power failure, load management or over use. The other is the Green Energy line, a low current phase which never fails! It is used only for lighting and small and light electronic appliances. It is a limited energy line.

"Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services."


That means, so much kWhr for a month, beyond which the line will trip off for the month. This Green Line is augmented by solar, wind or tidal electricity. That way this Green Line is Uninterrupted, but Energy Limited. This will bring a sense of responsibility on the consumer, who will plan the usage of his Green Power Line carefully.
