Circuit measures Currents in dc Servo motor: 12/06/01 EDN Design Ideas / (added 1/05) The simple circuit design in Figure 1 lets you measure all components of a
current flowing in a dc servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the output by using a single-ended A/D converter. The current-sense
resistor, R1, has a value of 0. ... |

Circuit Measures
Small Current in DC Servo Motor: 12/07/01 EDN-Design Ideas / (added 9/05) The simple circuit design in Figure 1 lets you measure all components of a current flowing in a dc
servo motor. The rectified output of the circuit uses ground as a reference, so you can measure the output by using a single-ended A/D converter. The current-sense resistor, R1, has a value of
0.1Ω. The Zetex (www.zetex.com) ZXCT1010 IC converts the differential signal across R1 to a single-ended signal. Two of these ICs form a signal rectifier..... |

Current Sense Curcuit Collection: AN105 - Linear Technology - Sensing and/or controlling current flow is a fundamental
requirement in many electronics systems, and the techniques to do so are as diverse as the applications themselves. This Application Note compiles solutions to current sensing problems and
organizes the solutions by general application type. These circuits have been culled from a variety of Linear Technology documents. |

Current sensing scheme improves PFC on/off sequences: 06/27/02 EDN - Design Ideas / (Electronic circuit added 10/03) PFC (power-factor-correction)
preconverters typically use the step-up, or boost, configuration, because this type of converter is relatively easy to implement (Figure 1). However, this topology requires the output voltage
to be higher than the input voltage. When this condition is not the case—for example, with on/off sequences or under load conditions—some inrush current flows thro.... |
