Patent ES-371704-A1 (ES)
Title: Differential amplifier
IPC: H03F3/45
Filed: 1969-09-20
Abstract: An integrated differential amplifier circuit providing high voltage gain over a wide range of quiescent current levels comprises a longtailed pair 11, 12 (Fig. 1) with a collector load comprising transistors 14-18 interconnected as shown. The output of transistor 16 is inverted at 26 and combined with the output of 17 to provide an amplifier output at 27. The collectoremitter voltages at 14, 15 are substantially constant and equal to the sum of the base emitter voltages across transistors 16 or 17 and 18. Common mode signals, i.e. changes in quiescent current, produced by changing the base bias on transistor 13 will not affect the collector-emitter voltages of transistors 14, 15, and hence will not affect the outputs of transistors 16 and 17. However, for differential signals, transistors 14, 15 present a high impedance since their base drive, determined by the current through 16, 17, 18, is unchanged. Differential signals will therefore be passed to the output 27. In a modification (Fig. 2), transistors 28, 30 have ##103 and a collectorbase breakdown voltage of about one volt. Cascade connected transistors 29, 31 biased through base emitter junctions 32, 33 ensure that the collector-base voltages of transistors 28, 30 are zero, thus reducing collector-base leakage current. A transistor 41 provides initial conduction in transistor 18. A pair of transistors (35, 36, Fig. 3, not shown) may be cascodeconnected to transistors (1711, 1811) in a manner similar to transistors 28, 30, 29, 31, to maintain equal gain in both halves of the amplifier. A further transistor (40) provides initial conduction in the base-emitter junctions controlling the cascode connected transistors (35, 36).

Title: Indicating apparatus
IPC: H02H3/33
Filed: 1976-12-10
Abstract: Self-powered apparatus for indicating the existence of a fault in any of a plurality of conductors in an multiconductor electrical distribution system. The plurality of conductors pass through the window of a closed loop core structure current transformer, and the current transformer has a power output and a signal output. The power output is connected to, and drives, fault indicating means and starting means. The starting means initiate operation of control signal translation means which are connected to the current transformer signal output. Also included are transmission means connected to the control signal translation means and to prevention means incorporated within the indicating means, and the transmission means transmit the control signal from the signal translation means to the prevention means. The indicating means are responsive to operation of the prevention means, such that only when the control signal is transmitted to the prevention means will the indicating means be allowed to operate. The entire apparatus is powered only during the existence of a fault, and derives its power by the fault's causing current to flow within the current transformer. The apparatus may also be utilized in a current-monitoring function for a single conductor.
