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 circuit in
Figure 1. |

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 no latching. 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 |
