  1. Stephen Woodward EDN Since the dawn of time or at least since the dawn of precision electronics a major headache for analog designers has been CMV (common-mode-voltage)-induced errors, also known as the dreaded ground loop. Although almost mystical ...

  2. Steven Galecki Electronic Design This circuit automatically attenuates a high voltage by known factors so that it matches the ADC input range for best converter resolution. It's a common challenge to measure voltages that exceed the operating ...

  3. Guus Colman EDN In many applications, the frequency-conversion steps comprise a buffer, preferably with some extra voltage gain; a mixer; and some filtering. Instead of including an amplifier in front of the mixer, you can easily integrate the ...

  4. Art Hogrefe EDN A number of circuits, such as level detectors and AM demodulators, benefit from a rectifier with a low offset voltage. Silicon diodes have an offset of approximately 0.6 V and do not work well in low-level circuitry. A Schottky ...

  5. Carl Pugh EDN Most circuits use bypass capacitors and can deliver substandard performance if the capacitors have poor pulse characteristics. Few if any articles cover how to test bypass capacitors for pulse characteristics. The circuit in Figure 1 ...

  6. Ron Mancini EDN One problem with standard FET gain-control circuits is increased noise when you use the FET as a part of a resistive attenuator in series with an op amp. This configuration attenuates the signal before amplification; hence, it ...

  7. Thomas Mosteller, Linear Technology EDN Despite the long-predicted demise of the 4- to 20-mA current loop, this analog interface is still the most common method of connecting current-loop sources to a sensing circuit. This interface requires the ...

  8. John Wynne EDN Digital potentiometers, such as Analog Devices’ AD5160 , make excellent digitally controlled voltage dividers in applications in which 8-bit resolution is acceptable. This Design Idea shows how to use a CMOS DAC as a voltage ...

  9. K Suresh EDN When you develop the prototype of a circuit using capacitors or when you replace an old, defective capacitor with a new one, you often need to know the value of the capacitor you use or replace. At times, the values printed on the ...

  10. Stephen Woodward EDN An inexpensive way to implement high-resolution digital-to-analog conversion is to combine microcontroller-PWM (pulse-width-modulated) outputs with precision analog-voltage references, CMOS switches, and analog filtering ( ...
