- Einar Abell EDN This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation (better than 1% over most of ...May 2, 2015
- .. charging circuit work with a more constant input voltage. Calculations for C1 C1 discharges at the rate of dV/dt = I/C = 10 V/ms. This is almost order of magnitude slower than the sinusoidal change of the input voltage from 330 V to 0 V that ...Oct 22, 2015
- .. Function and Benefits The circuit shown in Figure 1 provides a programmable 20-bit voltage with an output range −10 V to +10 V, 1 LSB integral nonlinearity, 1 LSB differential nonlinearity, and low noise. The digital input to the ...Apr 19, 2016
- Dusan Ponikvar.. You can use the circuit in Figure 2 to overcome these problems. Two standard transformers, T 1 and T 2 (220 V ac to 6 V ac, 10 W), are used to make an isolated replica of the mains supply, V M . This replica is doubled and rectified using D 1 , ...Apr 28, 2016
- .. small amount of power to analog/digital circuits, such as the LMH6672 DSL op amp. Figure 1. This simple circuit provides a 10 V power source from −48 V telecom power rails. The LMV431 voltage reference, along with the voltage-setting ...Apr 17, 2018
- .. The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 MHz than buying a 1- or 10-GHz ...Aug 23, 2018
- .. and practical diagrams of stable current generators with a variable or step action of terminal current from 1 µA to 10 nA are given. A stable current generator (SCG) is an electronic circuit designed to provide a constant current ...Dec 10, 2018
- .. S. Cook hackster.io In this project, I am showing you how to build a digital laser tachometer based on Arduino for around 10$. If you need to measure rotational speed, you can just buy it or do it yourself and learn something while building ...May 10, 2020
- .. its own power-supply voltage and the current that Q 3 provides. At power-on, Q 2 , Q 3 , and Q 4 are all off. Resistor R 10 draws a small amount of start-up current, which Q 3 amplifies to start the current-mirror process. When sufficient ...Sep 10, 2020
- Stefan WagnerCircuits Microcontrollers Usage Microchip ATtiny10 Attiny13 ATtiny24 ATtiny25 ATtiny44 ATtiny45 ATtiny84 ATtiny85.. an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its 10% accuracy is often insufficient. Fortunately, the oscillator can be calibrated, increasing its accuracy to 2% or ...Aug 4, 2021
