FIELD: electrical engineering. SUBSTANCE: current generator includes voltage generator, analog-to- digital converter, comparator of fixation of zero, flip-flop, 2N NOT-AND gates of logic multiplication, power supply source of constant positive voltage, power supply source of constant negative voltage, N discharge generators of stabilized current of positive polarity of same type, N discharge generators of stabilized current of negative polarity of the same type. Output of generator is connected to input of analog-to-digital converter and input of comparator of fixation of zero which output is linked to input of flip-flop. Outputs of flip-flop are connected to one of inputs of corresponding NOT-AND gates of logic multiplication. Their second inputs are connected to corresponding outputs of analog-to-digital converter. Outputs of NOT-AND gates of logic multiplication are connected to controlling inputs of proper discharge generators of stabilized currents of positive and negative polarity. Second inputs of discharge generators of stabilized current of positive polarity are linked to output of power supply source of positive voltage, second inputs of discharge generators of stabilized current of negative polarity - to output of power supply source of constant negative voltage. Outputs of all discharge generators of stabilized currents are interconnected and form output of current generator. EFFECT: improved reliability of generation of stabilized currents. |
