Filed: 1982-06-28
Abstract: PURPOSE:To set optionally the current transfer rate, by designing the system that the ratio of an output current of a current control element group to that of an element group is the ratio of the numbers of current control elements constituting respective circuits. CONSTITUTION:The ratio of a current i1 flowing to the current control element group 1 to a current i2 flowing to a current control element group 2 is equal (1:1) to the ratio of the number of elements of the element group 1 to the element group 2-1(100:100=1:1), since the current flowing to FETQa-1-Qa-100, and Qb-1-Qb-100 is equal, when terminals G1, G2 are kept for the same potential and the gate potential of the FETQa-1-Qa-100 and Qb-1-Qb-100 is kept equal and a current is applied to terminals D1, D2. Further, in applying a current to terminals D1, D2a, D2b, the ratio of the currents i1, i2 is equal (1:3) to the ratio of element number of the element group 1 and the groups 2-1 and 2-2 [100:(100+ 200)=1:3)].

Title: Output circuit of electronic equipment
Inventor: UEMURA YOUICHIROU
IPC: H03K17/78
Filed: 1981-07-16
Abstract: PURPOSE:To use either of a sink and a source current load, by connecting a transistor (TR) applied with a control signal through a diode in series to another TR biased by a power source, and putting both the TRs in complementary operation. CONSTITUTION:When the output of a logical circuit 1 is ''0'', a TRQ2 turns off, so a TRQ1 is applied with a bias through a resistance R5 and a diode D1 to turn on. Therefore, no sink current flows through a sink load IN. When the output of the logical circuit 1 is ''1'', on the other hand, the TRQ2 turns on. Then, reverse biasing is performed between the base and emitter of the TRQ1, which turns off. Further, a sink current flows to the sink load IN2 through the TRQ2. When the load is a source current load, the source current flows through the TRQ1.
