  1. Aaron Lager EDN Using LEDs has gained popularity as a method of saving power for general-purpose lighting, but an efficient method for driving them has also become a necessity. For example, Lumileds' Luxeon devices create lighting effects or ...

  3. Henno Normet Electronic Design The amplifier within a standard AV receiver can become a fully adjustable, three-phase power supply by adding a general-purpose op amp, a few passive components, and some standard transformers. If you need an ...

  4. Moshe Gerstanhaber EDN State-of-the-art ADCs accept differential inputs, allowing you to differentially implement the entire signal path from sensor to converter. This structure provides significant performance advantages, because differential ...

  1. Dave Conrad EDN A typical driver for thermoelectric (TE) cooler applications may use pulse width modulation (PWM) to drive an H-bridge circuit. This scheme works but drives the TE device with very large current pulses. These square waves, which are ...

  2. Raju Baddi EDN When designing logic for higher-than-usual supply voltages, such as 24 V, you can use a voltage regulator with a standard logic family and interface it through level shifters. Alternatively, if the logic is not too complex and the ...

  3. Derek Bowers Electronic Design Early radio receivers and record players nearly always had a knob marked “tone,” which was usually a crude low-pass filter with some form of severity adjustment. At best, these controls could partially ...

  4. Chuck Wojslaw EDN Figure 1. This schematic depicts a basic voltage-to-frequency converter. The basic VFC (voltage-to-frequency converter) in Figure 1 comprises an integrator (IC 1 ) and a Schmitt-trigger circuit (IC 2 ). The integrator converts the ...

  5. Aaron Lager EDN Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to turn a 555 PWM circuit into an ...

    Minh-Tam Nguyen, Maxim Integrated EDN Unlike the four-wire SPI, QSPI, and Microwire data-interface standards, I 2 C and SBBus buses require only two wires for data transmission, because they send and receive over the same wire. The circuit in ...
