Circuit forms high frequency polarity clamp: 04/11/2002
EDN - Design Ideas / You need a negative signal clamp to protect
an ADC against negative-going signals while measuring the
positive pulse shape of the signal by digitizing the waveform.
In other words, you must clamp negative signals at 0V. The

Eliminate Latching Current Limit In Power Supplies :
08/05/02 Electronic Design - Ideas for Design / Most modern
power-supply control ICs offer built-in overcurrent or
short-circuit protection. While some overcurrent-protection
schemes are latching, others are nonlatching. When the
overcurrent trip level is reached in a latching controller,
the... |

Passive circuit limits inrush current: 09/26/2002 EDN
- Design Ideas / You would normally limit the inrush current
during start-up of a rectifier circuit with a capacitor output
filter by using the circuit in Figure 1. You insert a high
resistance in series with the ac input or the dc output of the
rectifier and then short-circuit the resistance with a switch
once the filter capacitor is sufficiently charged |
