limited space-charge accumulation mode

[¦lim·əd·əd ‚spās ‚chärj ə‚kyü·myə′lā·shən‚mōd]

(electronics)

A mode of operation of a Gunn diode in which the frequency of operation is set by a resonant circuit to be much higher than the transit-time frequency so that domains have insufficient time to form while the field is above threshold and, as a result, the sample is maintained in the negative conductance state during a large fraction of the voltage cycle. Abbreviated LSA mode.
