ANALOGUE MULTIPLIER OF VOLTAGES Russian patent published in 2010 - IPC G06G7/12 G05F3/26 H03F3/34 

FIELD: radio engineering.

SUBSTANCE: device comprises the first source of the first multiplied voltage u_x, the second source of the first multiplied voltage u_x antiphased to the first source, the first and second antiphased sources of the second multiplied voltage u_y, the first, second, third and fourth input transistors, the first and second current-stabilising two-terminal networks, the first load element, new connections are included - base of the second inlet transistor is connected to the first source of the second multiplied voltage u_y, base of the fourth inlet transistor is connected to the second source of the second multiplied voltage u_y, besides between emitter of the first input transistor and bus of power supply source there is the first additional capacitor connected by alternating current, and between emitter of the third input transistor and bus of power supply source there is the second additional capacitor connected by alternating current.

EFFECT: reduced supply voltage of AVM by increasing symmetry of u_x voltage transfer channels, increased capacity of u_x and u_y multiplication at high frequencies.
