Description

Предметом изобретени   вл етс  устройство дл  усилени  малых напр жений посто нного тока с коммутацией усиливаемого и референсного напр жений на вход усилител  и с синхронной коммутацией выхода усилител  на приспособление дл  получени  отношени  усиливаемго и референсного напр жений.The subject of the invention is a device for amplifying small DC voltages with switching amplified and reference voltages at the input of the amplifier and with synchronous switching of the output of the amplifier against the device for obtaining the ratio of amplifiable and reference voltages.

Предлагаемый метод усилител  малых напр жений основан на преобразовании двух напр жений (напр жени  EI от стандартного источника, например нормального элемента и усиливаемого напр жени  2) в импульсные напр жени  с амплитудами импульсов Ll и L2, пропорциональных и Е так, что, , 112 .The proposed low voltage amplifier method is based on converting two voltages (EI voltages from a standard source, for example, a normal element and an amplified voltage 2) into pulsed voltages with amplitudes Ll and L2, proportional to and E, such that,, 112.

Схема предлагаемого устройства изображена на приложенном чертеже. Получение импульсных напр жений осуществл етс  при помощи переменного конденсатора специального типа, например с одной группой подвижных пластин А и двум  группами неподвижных пластин Si и В.The scheme of the proposed device is shown in the attached drawing. Impulse voltages are obtained using a special type of variable capacitor, for example, with one group of moving plates A and two groups of fixed plates Si and B.

При введении (или выведении) группы пластин А в груипу сатоторных пластин В между точками ав получаетс  импульс напр жени  с амплитудой, определ емой напр жением Яи соответственно при введении (или выведении) роторных пластин .4 в группу пластин В между точками ав получитс  импульс напр жени  с амплитудо , пропорциональной значению напр жени  Е. Продолжительность этих импульсов определ етс  скоростью перемещени  роторных пластин и геометрией конденсатора, котора  также определ ет форму импульса.When introducing (or removing) a group of plates A, in a group of satellite plates B between the points av, a voltage pulse is obtained with an amplitude determined by the voltage Yi, respectively, when introducing (or removing) the rotor plates.4 into the group B plates between the points av Amplitude proportional to the value of voltage E. The duration of these pulses is determined by the speed of movement of the rotor plates and the geometry of the capacitor, which also determines the shape of the pulse.

Таким образом, при периодическом движении пластин .4 между пластинами В и Sj на входе усилител  У (между точками ав получаетс  напр жение в виде чередующихс  импульсов с амплитудами, пропорциональными напр жерги м Е и Е. На выходе усилител  У получитс  напр жение в виде импульсов с амплитудами L/i jj , иThus, by periodically moving the plates .4 between the plates B and Sj at the input of amplifier Y (between points av, a voltage is obtained in the form of alternating pulses with amplitudes proportional to the voltage E and E. The output of the amplifier Y will receive a voltage with amplitudes L / i jj, and
