11. Correct voltage drop and phase shift in transmission lines
    Ron Shakery
    Analogue Design Texas Instruments THS4551
    Many precision test-and-measurement and high-speed analog applications require an exact targeted voltage to be delivered to the device under test or intended load to accurately analyze the device. Design and test engineers are well-aware that this ...

12. Minimizing passive PWM ripple filter output impedance: How low can you go?
    Stephen Woodward
    Signal Processing, Filters Texas Instruments TLV2374 TMUX4053
    Simplicity and low cost sustain the popularity of passive PWM DAC ripple filters despite their limitations. One of these limitations is a high output impedance caused by the series sum of filter resistance(s) (R F in Figure 1, one resistor for each ...

13. My favorite design idea of all time…
    Steve Hageman
    Analogue Design Texas Instruments LM318
    The editors of EDN will tell you that the Design Ideas section is the most popular section of the website, this goes back to the print editions, where that was the first section that most if not all readers turned to first upon getting a new issue. ...

14. Squeeze extra resolution from an 8-bit DAC with Shannon decoder idea
    Stephen Woodward
    Signal Processing, Filters Texas Instruments TLV2371 TLV5624
    When someone notices that two 8-bit DACs can be bought for less than one 16-bit DAC, a classic question is often asked: Why can’t you simply take two 8-bit DACs, assign one to the MSByte, the other to the LSByte, sum their outputs in a 28:1 ...

15. A safe adjustable regulator
    Peter Demchenko
    Supply Texas Instruments LM350
    Figure 1 shows a typical using of LM350 ( LM317 ) adjustable regulator when you need to adjust its output voltage. Figure 1. This voltage is approximately given here as: The potentiometer R2 is often the most unreliable part of the circuit. As ...

16. Two wires carry power and data
    Robert Hanrahan
    Interfaces Supply Texas Instruments COP888xG/CS LMC7211 LMV7239 LP2952 LP3990
    At times, designers face a limited amount of wire and/or a limited cost to communicate with a remote device such as a sensor. Many devices allow communication over an ac or dc power line employing an AM or FM modulation scheme. However, they tend ...

17. Circuits protect outputs against overvoltage
    Dimitri Danyuk
    Measurement Supply Texas Instruments OPA551
    In test-and-measurement applications, you must provide overvoltage protection for the output terminals of amplifiers, power supplies, and similar components. The conventional way to accomplish this task is to add series resistors with the output ...

18. The Shannon decoder: A (much) faster alternative to the PWM DAC
    Stephen Woodward
    Signal Processing, Filters Texas Instruments CD74HC4053
    Readers will recognize the famous name Claude Elwood Shannon, widely renowned as the “father of information theory” and originator of many discoveries and inventions. Among these is an elegant and pioneering (First published in 1948!) ...

19. Single Op Amp Achieves Double-Hysteresis-Transfer Characteristic
    Encarna García Herminio Martinez Juan Gámiz
    Analogue Design Texas Instruments TL081 LM311
    In process-control applications requiring discontinuous controllers, the most elementary choice is a two-position-mode or on/off controller. A typical example of such a controller is a space heater. If the temperature drops below a setpoint, the ...

20. AC/DC power-supply startup considerations for PMDC motor loads
    Ben Lough
    Supply Texas Instruments TL331 UCC256402
    Permanent magnet DC (PMDC) motors offer smaller solution size and increased efficiency in applications such as portable vacuums and cordless electric power tools. When designing an isolated power supply for PMDC motors, there are several ...
