FIELD: radio equipment.
SUBSTANCE: differential cascade (DC) comprises current outputs of the device matched with the first power supply bus, field-effect transistors with connected sources and connected to each other. Third and fourth additional resistors are introduced into the cascade for setting the specified value of the DC limitation voltage, the change in the resistance of which substantially influences both the maximum output currents DC and the voltage of limitation of its pass characteristic.
EFFECT: technical result consists in creation of conditions, at which possibility of variation of voltage of limiting passage characteristic Ugr depending on specified values of SR at fixed current consumption is provided.
