32. Minimize noise and ripple with a low-noise buck converter
    Supply Texas Instruments TPS62912 TPS62913
    Minimizing noise is a common challenge for engineers designing a power supply for noise-sensitive systems for test and measurement and radio applications, such as clocks, data converters or amplifiers. Although the term “noise” can mean ...

33. Design low-duty-cycle timer circuits
    Oscillators Texas Instruments TLC555D
    Designing astable circuits using the industry-standard 555 timer is a straightforward process when duty cycles are 50% or greater. However, you must overcome the many pitfalls of low-duty-cycle circuits to arrive at a desired result. Using only ...

34. Tips and tricks for optimizing your voltage supervisor
    Microcontrollers Supply Texas Instruments TPS3700 TPS3701 TPS3710 TPS3890 TPS386000
    Voltage supervisors have provided analog voltage monitoring to digital circuits for decades. Texas Instruments released the original TL7705 in 1983; it consumed 1.8 mA, came in a plastic dual-inline package (PDIP) and you can still purchase it ...

35. Gated Oscillator Starts without Delay
    Oscillators Texas Instruments CD74HC132
    Electronic Design Proper component selection can help reduce startup time for gated oscillators. Gated oscillators always present the typical problem of having a delay when a digital input control signal enables its oscillation. This delay happens ...

36. Variable gain superbal circuit preserves CMRR
    Amplifiers Texas Instruments NE5532
    EDN The superbal circuit will be familiar to anyone involved in balanced signal transmission [1,2]; it is a differential amplifier which presents identical input impedances to both legs of a balanced line. Balanced loading is a necessity for the ...

37. What's All This Unused Input Stuff, Anyhow?
    Theory Texas Instruments LM6584MT
    Paul Rako Electronic Design You can’t leave unused inputs floating, but you might not want to connect them to a power or ground rail either. Digital engineers learned long ago that they should not leave unused inputs unconnected. CMOS chip ...

38. Shunt regulator speeds power supply's start-up
    Laser Supply Texas Instruments UC3853N TL431A
    By Michael O'Loughlin EDN In certain applications, design requirements may call upon a system's switched-mode power supply to more promptly deliver its output than would the garden-variety power supply. Figure 1 shows such a supply's ...

39. Dynamically adjust negative output voltages
    Supply Texas Instruments LM4040
    by Pradeep Shenoy, Texas Instruments EDN There are standard techniques to generate negative output voltages, and there are well-known approaches to dynamically adjust an output voltage. The missing link that I hope to address in this article ...

40. E-fuses: warming up to higher-current applications
    Supply Texas Instruments TPS25925 TPS25926
    As a cautious analog-centric engineer, I have always liked traditional thermal-based fuses and been somewhat skeptical of electronic fuses (also written as e-fuses or eFuses) due to their active components. After all, when it comes to reliability, ...
