BARITT diode.

There are three conditions for proper BARITT operation:

1. The electrical field across the device must be great enough to force charge

carriers in motion to drift at the saturation velocity (10 7 cm/s).

2. The electrical field must be great enough to create the punch-through con-

dition.

3. The electrical field must not be great enough to cause avalanching to occur.

The normal circuit configuration for BARITT devices is in a resonant

LC

tank or

cavity. At turn-on, noise pulses will initially shock excite the resonant circuit into
