Circuit Detects Loss of 4-20 Ma Signal - National Semiconductor Application Note
(app note added 6/06) |

Circuit distorts duty cycle for CML inputs - 08/05/04 EDN-Design Ideas: To
test a gigabit-speed data-recovery chip, you need a clock with a controllable duty
cycle. Because most pattern and clock generators have a fixed duty-cycle output of
50%, the design may require a small circuit to distort the duty cycle. The signal with
controllable duty cycle drives a standard CML (current-mode-logic)input with
on-chip.....(design idea added 02/05) |

Circuit eases power-sequence testing - 07/09/09 EDN A low-cost design
controls power-up of two power sources.....(design idea added 08/09) |
|
Circuit eases three phase monitoring - 12/17/98 EDN-Design Ideas:
Measuring line-to-line voltages in a delta-connected three-phase system can present
special problems. Because all three lines may be floating several hundred volts above
ground, you can not use nonisolated, grounded oscilloscopes or other single-ended
instruments. Special isolation amplifiers.....(design idea added 2/06) |

Circuit Measures Currents in DC Servo Motor - 12/06/01 EDN-Design Ideas: 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 of0.....(design idea added 1/05) |
