It has USB ports for connecting a keyboard and mouse, and a video output port for ... 13-09-2017 Luca Bruno EDN You can use the circuit in Figure 1 to obtain a low regulated voltage, such as 5 V dc, from a higher voltage, rectified, sinusoidal voltage source without resorting to an electrically noisy dc/dc converter or wasting watts in a ... 12-09-2017 Ricardo Jiménez, Fernando D. Pacheco, and Blanca L. Rodríguez Electronic Design Measuring the low frequencies that are common in many real-world situations, such as biomedical or speedometer applications, is a challenge due to the ... 12-09-2017 Stefan Strozecki EDN Many applications require current sources rather than voltage sources. When you need a high-current source, using a linear regulator is inadvisable, because of the high power dissipation in the series resistor. To solve the ... 05-09-2017 Marián Štofka EDN Many applications require a sampling circuit whose output is inverted with regard to the respective sample of an input signal. A simple approach is a cascade of a common noninverting sample-and-hold amplifier and an ... 31-08-2017 Jordan Dimitrov EDN [Editor’s note: This programmable DC reference calibrator will make a great DIY project for your lab bench. Full design files for the analog portion are provided, leaving the microcontroller part up to you. Send me your ... 29-08-2017 Bill Reeve Electronic Design By adding only a few components, you can turn a temperature- and beta-compensated current sink into a common-emitter (CE) amplifier that maintains a stable biased operating point. This architecture is useful for ... 23-08-2017 Abhijeet Deshpande EDN Properly maintained rechargeable batteries can provide good service and long life. Maintenance involves regular monitoring of battery voltage. The circuit in Figure 1 works in most rechargeable batteries. It comprises a ... 17-08-2017 Alex Rysin Electronic Design Limiter circuits are often needed to prevent a wide-range signal from overloading the next stage in the signal chain this user-adjustable circuit provides bipolar limiting at precise preset value. As the name implies, a ... 17-08-2017 T A Babu EDN The key features of this Design Idea are: Soft switch on/off operation Zero current drain in sleep mode Two level dimming Low battery protection Simple controller based on CMOS CD4017 Johnson counter The circuit is divided into two ... 10-08-2017
