- Dave WuchinichMany LED drivers, using both charge pumps and inductors, are available to boost the 1.2 to 2.4 V available from single- and dual-cell NiMH (nickel-metal-hydride) batteries to the 3.6 V that white LEDs require. However, most of these circuits, such ...Apr 18, 2022
- Shyam TiwariYou face a serious problem in using a slow ADC with a fast peak detector. The circuit in Figure 1 allows a slow ADC to measure a fast, sampled signal peak. The 100-MHz peak detector for ultrasonic-pulse sampling uses a fast MAX4231 amplifier. This ...Apr 5, 2022
- John GuyTo implement a step-up converter with a current output, designers often simply connect the load in place of the top resistor in a resistive-divider feedback network. The bottom resistor then serves as a current-sense resistor. Though simple, this ...Mar 6, 2022
- James HorsteLarge analog systems that present many loads to a voltage-reference source can often demand more current than a single reference IC can deliver. However, if the reference IC includes force and sense terminals, you can easily add a buffer to the ...Mar 3, 2022
- Arpit Mehta Prashanth HolenarsipurCertain current-sense amplifiers have to contend with frequent overvoltages. For example, a current-sense amplifier that monitors battery discharge currents in an automobile must withstand high-voltage load dump pulses produced when loads are ...Feb 23, 2022
- Mark PearsonPortable systems often use LEDs of different colors and in varying quantities of each color. Some examples are white for the display backlight, green for keypad illumination, and red for power. Typically, the LEDs derive power from at least two ...Feb 9, 2022
- Ken YangMany low-dropout-voltage regulators see service in electronic systems, but relatively few are designed for low-noise operation. (For example, Maxim's MAX8887 achieves a noise voltage of approximately 42 µV rms.) However, certain ...Feb 1, 2022
- Alfredo Saab Tina AlikahiThe best way to make midrange, low- to medium-accuracy temperature measurements (considering size, cost, performance, and ease of use) is to use an IC temperature sensor. But most IC temperature sensors are designed for applications where the ...Jan 3, 2022
- John GuyAmplifying the human voice presents some tough challenges. One of the toughest of these is providing enough amplification to make sure a soft-spoken person can be heard while allowing sufficient headroom for people who speak loudly. If the ...Dec 27, 2021
- Bill O'NeilIn addition to the traditional lead-acid battery, modern electric/hybrid cars often include a large capacitor (40 F or more) as a backup power source. Located under the rear seat, this capacitor ensures an extra 10 to 15 minutes of driving time ...Dec 9, 2021
