摘要： A linear-gain amplifier arrangement comprises a current amplifying cell constructed by means of field-effect transistors and comprising a first (M1, M3) and a second (M2, M4) current-mirror circuit whose respective input transistors (M1; M2) and output transistors (M3; M4) constitute a first and a second differential pair. The input transistors (M1; M2) have their drain electrodes connected to a voltage-current converter (V/I) comprising field-effect transistors, which supplies difference currents (I in1 , I in2 ) which are square-law functions of the input voltage (U in ) to be amplified. The difference between these input currents (I in1 ; I in2 ) is a linear function of the input voltage (U in ). When the transistors are operated in their saturation regions the difference between the output currents (I out1 ; I out2 ) is also a linear function of the input voltage (U in ). By adding a direct voltage (V c ) to the gate-source voltage of the input and output transistors (M1, M2; M3, M4) or by adding a direct current (I c ) to the respective input currents (I in1 ; I in2 ) the gain can be varied without a change in bandwidth. When the arrangement is constructed as an integrated semiconductor circuit its gain can be made immune to temperature variations and tolerances in the fabrication process.

摘要： The invention relates to a current amplifier comprising an input terminal (1) for receiving an input current, an output terminal (2) for supplying an output current, a first transistor (T₁) having a base-emitter junction coupled to the input terminal, and a second transistor (T₂) having a collector coupled to the output terminal and having an emitter arranged in series with a voltage source (4), the series arrangement of the voltage source and the base-emitter junction of the second transistor being arranged in parallel with the base-emitter junction of the first transistor, the first transistor being of the NPN conductivity type and the second transistor being of the PNP conductivity type. The low internal series resistor of the NPN transistor T₁ allows a comparatively large input current I in , so that the attenuated output current (I out ) is a linear function of the input current over a wide range. This results in a current-sourcing attenuating current mirror having a far better linearity than a current amplifier in which the first and the second transistor are both of the PNP conductivity type.

摘要： A first and a second transistor (T,, T 2 ) whose emitters are connected to a common point (4) via first resistors (R 1 , R 2 ), which common point is connected to the positive power-supply terminal via a current source (I 1 ), form a differential amplifier to which an input signal (V i ) is applied. In order to increase the slew rate the quiescent current through the first and the second transistor (T 1 , T 2 ) is made to increase when the input voltage (V i ) increases. This is achieved by means of a third transistor (T 3 ) whose emitter is connected to the common point (4). The base of this transistor (T 3 ) is connected to the tapping of a voltage divider which is arranged between the bases of the first and the second transistor (T 1 , T 2 ) and which comprises second resistors (R 3 , R 4 ). When the input voltage increases the transistor (T 3 ) drains a continually decreasing portion of the current from the current source (I 1 ).

摘要： An arrangement is proposed for measuring a quiescent current of a digital IC. The arrangement comprises a current sensor in series with the IC and the supply, voltage stabilization means for stabilizing the voltage across the IC and signal processing means coupled thereto for processing the measured quiescent current. The quiescent current is measured when no flip-flops are switched in the IC. By means of the arrangement, there can be measured rapidly and accurately whether the quiescent current assumes an abnormal value, which indicates that the IC exhibits defects. The signal processing means comprise a current mirror, which is coupled to a current comparator circuit supplying a digital output signal for determining a defect.

摘要： A amplifier circuit comprises a first transistor (T₁) and a second transistor (T₂) whose emitters are each connected via a first resistor (R₁) to a point (2) which is connected to the power-supply terminal (3) by means of a current source (1). The bases of said transistors are connected to input terminals (4, 5) and via a second resistor (R₂) each to the base of a third transistor (T₃) whose emitter is connected to the terminal (2). The linearity of the circuit is improved by arranging a fourth transistor (T₄) and a fifth transistor (T₅) in series with the collector-emitter paths of the first transistor (T₁) and the second transistor (T₂) which fourth and fifth transistor have their bases connected to a reference terminal (7) and have their emitters interconnected by means of a third resistor (R₃).
