Abstract
PURPOSE: To make it possible to obtain the secondary output in direct proportion to the displacement of the core of a differential transformer, by amplifying a sine wave signal by a current amplifying circuit which has output terminals at a connecting point between two complementary transistors and that between two capacitors of the same capacity.
CONSTITUTION: Two complementary output transistors TR1 and TR2 are connected in series and this series circuit is connected to electric power source Vcc; and two capacitors C of the same capacity are also connected in series and this series circuit is connected to the electric power source. Then, a sine wave signal is amplified by current amplifying circuit 3 which has output terminals at the connecting point between both transistors TR1 and TR2 and that between both capcitors C and both terminals of the primary winding n1 of differential transformer 2 provided with diaplaceable core 1 to generate the secondary output corresponding to the displacement of core 1 are connected to both the output terminals of current amplifying circuit 3. Consequently, an input voltage across the primary winding of differential transformer 2 can be stabilized.
