31. 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 ...

32. 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 ...

33. 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 ...

34. 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 ...

35. 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 ...

36. 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, ...

37. Cascode Configuration Removes Miller Effect, Boosts PFC Performance
    Supply Texas Instruments LM78L15 UC3854AN
    The power factor corrector (PFC) front end of an off-line power supply is subject to the operating frequency limitation caused by the Miller Effect of its associated power MOSFET. This effect is a property of any transistor configuration with a ...

38. How to make a simple nonmagnetic AC/DC power supply
    Supply Texas Instruments TPS7A78 TLV704
    Texas Instruments When creating an industrial power supply, one of the most common challenges is transforming the AC voltage supply into a DC voltage supply. Changing an AC voltage to a DC voltage is necessary for nearly every application, from ...

39. Three low-side LED biasing topology options and their trade-offs
    Optoelectronics Analogue Design Texas Instruments DAC43608/53608
    Uttam Sahu, Texas Instruments Many imaging products are moving toward more efficient LED array-based solutions and away from traditional technologies such as lasers or lamps. Applying resistive voltage dividers enables the linear forward biasing of ...

40. How to Extend Battery Run-Time for Wearable Applications. Part 2
    Supply Texas Instruments bq24040 bq25100 bq27421-G1
    Paul Pickering Electronic Design Part 1 Let’s discuss the two most important blocks in a portable or wearable BMS: the battery charger and the battery fuel gauge. Battery Charger A battery charger must monitor the state of the Li-ion battery ...
