unilateralization

unilateralization

[‚yü·nə‚lad·ə·rə·lə′zā·shən]
(electronics)
Use of an external feedback circuit in a high-frequency transistor amplifier to prevent undesired oscillation by canceling both the resistive and reactive changes produced in the input circuit by internal voltage feedback; with neutralization, only the reactive changes are canceled.

Frequency stability is usually achieved by unilateralization; neutralization; selection of source and load admittances that result in a frequency stable amplifier; or by utilization of negative feedback elements while controlling the overall loop gain and phase shift of the amplifier.
Unilateralization consists of employing an external feedback network to achieve a composite [S.sub.12] of zero.
This is not as good as unilateralization in terms of total stability achieved but is simpler to achieve over a limited frequency range.
