Emission from Electronics Circuits: Common Study (1)

 #            Emissions directly proportional to:

1.        Power consumption.

2.       Slew rate.

3.       Clock speed.

4.       Ground Bounce.

5.       Output loading.

#             Short straight current element radiates:

1.       Proportional to current they carry.

2.       Proportional to electrical length.

3.       And increases with frequency.

#             Small current loops radiates

1.       Proportional to current.

2.       Square of the loop and frequency.
