The chip designer has to make some compromises to achieve the performance vendors of single-supply op amps claim for rail-to-rail input capability. Conditioning techniques for real-world sensors 28 Many real-world sensors produce low output voltages at low frequencies that require a signal conditioning circuit with high gain and accurate— close to dc—performance. We assess the state of the art in sensor signal conditioning for modern analog electronics. by Steve Taranovich, Senior Technical Editor Use S-parameters to describe crosstalk 14 S-parameter formalism, developed to describe the microwave properties of interconnects, offers a natural way of describing crosstalk. by Eric Bogatin & Alan Blankman, LeCroy 41 Mechatronics in Design: Taking that tough first step The ability to physically model differentiates engineers; it is not a commodity. 44 Tales from the Cube: A probe without a paper trail 19 Designing low-energy embedded systems from silicon to software produCt roundup 42 Power modules: Automotive image sensor A low-energy standby state can make a microcontroller seem extremely energy efficient, but its true performance is evident only after taking into account all of the factors governing active power consumption. by Keith Odland, Silicon Laboratories Inc DesigniDeas D2 34V T1 120V AC:12V AC + CSERIES 100 F/ 35V + CBOOST 100 F/ 35V 0V − BR1 + 37 Low-distortion discrete buffer amplifier handles bipolar signals 39 Single-ended-to-differential converter has resistor-programmable gain 40 Generate boost rails in a bridge-rectifier circuit V AC D1 17V D3 + CFILTER 1000 F/ 25V 0V 0V V AC 0V + CSERIES 100 F/ 35V + CBOOST 100 F/ 35V –17V D4 2 EDN EUROPE | JANUARY 2013 www.edn-europe.com http://www.edn-europe.com/renewal http://www.edn-europe.com
