Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) products use crystal oscillators to generate areference for the phase-locked loop (PLL)-based local oscillator (LO). This tuTorial provides a basic description of theISM-RF Crystal Calculator, which can be used to calculate various impacts on crystal frequency accuracy and startupmargin for such an LO.

Abstract: Mechanical misalignment and scaling factors lead to a mismatch between the values coming from a touchscreen panel (as translated by a touch screen controller) and the display (typically an LCD) on which the touch screenpanel is mounted. This tuTorial discusses how to calibrate the touch screen panel to match the display.

Abstract: It is incredible how many programmable logic controls (PLCs) around us make our modern life possible and pleasant.Machines in our homes heat and cool our air and water, as well as preserve and cook our food. This tuTorial explains the importanceof PLCs, and describes how to choose component parts using the parametric tools on the Maxim's website.A similar version of this article was published February 29, 2012 in John Day's Automotive Electronic News.

Abstract: This tuTorial discusses methods for digitally adjusting the output voltage of a DC-DC converter. The digital adjustmentmethods are with a digital-to-analog converter (DAC), a trim pot (digital potentiometer), and PWM output of a microprocessor.Each method is assessed and several DACs and digital potentiometers presented.

A tuTorial on SAR type A/D converters, this note contains detailed information on several 12-bit circuits. Comparator, clocking, and preamplifier designs are discussed. A final circuit gives a 12-bit conversion in 1.8µs. Appended sections explain the basic SAR technique and explore D/A considerations.

Abstract: It may sound trite, but it is definitely true: the smart grid has the potential to completely transform the energyindustry. However, smart meters and grid management alone will not ensure the success of the smart grid. Unliketraditional IT networks, smart grids require consideration of energy measurement and security. To completely optimize thistechnology, smart grid designs must focus on energy measurement and security. This tuTorial considers the benefits ofboth energy measurement and security and how they make machine-to-machine networks different from traditional IT.

Abstract: We don't expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can't solve all issues—each application has different ESD requirements.Knowing that "one size fits all" cannot apply to power design, the power designer, or the engineering"super hero," must consider all the potential disruptions to a steady flow of power and thenvarious waysto mitigate them. This tuTorial describes voltage- and current-limiting devices and risetime reducers tomanage the power. It also points to free and low-cost software tools to help design lowpass filters, checkcapacitor self-resonance, and simulate circuits.

Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to learn something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. Unfortunately,critical industrial infrastructure is not currently designed with security as a key goal, leaving open multipleavenues for an educated and funded attacker to create massive problems. This tuTorial outlines somebasic concepts that engineers and product definers should consider to make sure their new projects stayahead of future threats.

Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) receivers use an external Sallen-Key datafilter and a data slicer to generate the baseband digital output. This tuTorial describes the ISM-RF Baseband Calculator,which can be used to calculate the filter capacitor values and the data slicer RC components, while providing a visualexample of the baseband signals.
