CURRENT MULTIPLIER BASED ON ROOT CURRENT-VOLTAGE CHARACTERISTIC OF MOS TRANSISTOR Russian patent published in 2010 - IPC G06G7/16 

FIELD: electricity.

SUBSTANCE: circuit of current multiplier includes the first, second and third MOS transistors with common ratio of channel width to its length, and the first and second sources of current, which accordingly provide the first and second inlet currents that reflect the first and second multiplied multipliers. The first and second MOS transistors perform the first and second voltages as functions of the first and second inlet currents, and the third MOS transistor produces the third current as function of the first and second voltages. In response to the third current, circuit of current multiplier produces a signal of the first and second multipliers product.

EFFECT: reduced complexity of analog multiplier circuit.
