TWO-CYCLE AMPLIFIER Russian patent published in 2008 - IPC H03F3/26 

FIELD: radio engineering, possible use in sound frequency power amplifiers.

SUBSTANCE: two-cycle amplifier makes it possible to achieve high linearity at low saturation voltage due to "short" chain of signal passage with low phase delay in working range of frequencies. In suggested circuit currents of all cascades are limited, resulting in increased reliability of amplifier during overload.

EFFECT: invention ensures high qualitative parameters of amplifier when used in output two-cycle cascade of field MDS transistors of same conductivity.
