摘要： A class-G amplifier comprises first, second and third terminals connected to a load, first supply voltage (V.sub.1) and second supply voltage (V.sub.2), respectively, where V.sub.2 >V.sub.1. First (T.sub.1) and second (T.sub.2) transistors are series-connected between the first and third terminals with the collector of T.sub.1 coupled via first diode (D.sub.1) to the second terminal. A third emitter follower transistor (T.sub.3) has a B/E junction coupled between a signal input terminal and base of T.sub.1. A first current source (5) couples the third terminal and third transistor. A driver circuit includes a first current path between the third terminal and emitter of T.sub.3 comprising, in series, a second current source (7), a fourth transistor (T.sub.5) and second diode (D.sub.4). A second current path between a junction point (3) and common point (11) comprises, in series, third (D.sub.2) and fourth (D.sub.3) diodes and a third current source (8). Base of fourth transistor is connected to junction (9) and its collector is connected to third current source via fifth diode (D.sub.5). A low input voltage cuts off second transistior so first transistor connected to second terminal. Above a given voltage, driver circuit turns second transistor on so first transistor connected to third terminal. The output (2) thereby attains a voltage equal to second supply voltage (V.sub.2) minus one B/E voltage.

摘要： The invention relates to an integrated resistor formed in an epitaxial layer and provided with at least one tap. In order to reduce field effect action between the resistor and the epitaxial layer, the voltage on the two ends of the epitaxial layer underneath the resistor tracks the voltage on the two ends of the resistor. Moreover, the epitaxial layer is short-circuited by means of buried layers at the locations where the resistance layer also exhibits a short-circuit, such as underneath the contact area of the tap.

摘要： An amplifier arrangement having a first and a second output transistor, which are drain-connected to the output terminal. A driver stage (100), prevents the output transistors from becoming non-conductive, thereby reducing cross-over distortion. This is achieved by applying an input signal via the sources of a source coupled transistor pair to the gates of the output transistors. Additional source followers are provided for defining gate-sources voltages which prevent the output transistors from becoming non-conductive.

摘要： An integrated circuit, includes an output stage with an input which is coupled to a first and a second gate of an NMOS transistor and a PMOS transistor, respectively, and an output which is connected to a first and a second supply terminal via the PMOS transistor and the NMOS transistor, respectively. The output is coupled to the first gate via a series connection of a Miller capacitor and a switching circuit. The Miller capacitor limits the rate of increase of the voltage on the output, thus preventing interference. The switching circuit is rendered non-conductive ahead of the switching over from logic low to logic high. This prevents sudden discharging of the Miller capacitor which would otherwise cause interference itself.

摘要： A first signal processor stage of an audio amplifier arrangement influences the signal strength of a received audio signal for at least part of the frequency range of the received audio signal. An output amplifier stage amplifies the audio signal influenced by the first signal processor stage. The audio amplifier arrangement further includes a transformer having a primary winding connectable to a mains voltage and having a secondary winding connected to an AC/DC converter whose outputs are connected to at least the output amplifier stage for feeding the output amplifier stage. A detection circuit generates a detection signal (Vms) which is related to the power load of the transformer. An analysis circuit detects in response to the detection signal whether the rise in temperature occurring in the transformer due to the power load has exceeded a specific norm. The analysis circuit includes a control circuit for reducing the signal strength of the received audio signal for at least the part of the frequency range in the case where a transgression of the norm is detected.

摘要： An amplifier arrangement which includes a first and a second output transistor each having a base, a collector and an emitter. A bias stage generates a bias voltage between the bases of the first and the second output transistor. The emitters of the first and the second output transistors are coupled to an output terminal. The bias voltage has a negative thermal response, and one element (e.g. a transistor) of the bias stage is thermally coupled to the first and the second output transistor. In order to preclude thermal instability of the amplifier arrangement, the bias stage is adapted to generate a first voltage having a first negative thermal response by means of the one element of the bias stage and to generate a second voltage opposite to the first voltage and having a second negative thermal response. The bias voltage is equal to the sum of the first and the second voltages, the first voltage being larger in absolute value than the second voltage. The negative thermal response of the bias voltage is determined by the effect of the first and the second negative thermal response, and the first negative thermal response is larger in absolute value than the second negative thermal response.

摘要： For a satisfactory cross-over behavior of the transistors T.sub.1 and T.sub.2 of push-pull amplifier comprising an input 2 and an output 3, it is necessary that the sum of the base-emitter voltages of the transistors T.sub.1 and T.sub.2 remains substantially constant. For this purpose a first voltage-current converter 5 is coupled between the base and the emitter of transistor T.sub.1, the inverting input of this converter being coupled to the base of transistor T.sub.1 via a first reference-voltage source 8 and the non-inverting input to the emitter of transistor T.sub.1. Similarly, a second voltage-current converter 9 and a second reference-voltage source 12 are arranged between the base and the emitter of transistor T.sub.2. The output currents of the first and the second voltage-current converters 5 and 9 are compared with each other in the combining circuit 14 which drives the control amplifier 15, which in its turn controls the base-emitter voltage of transistor T.sub.2 in such a way that the sum of the base-emitter voltages of transistor T.sub.1 and T.sub.2 remains constant. The push-pull amplifier exhibits a minimal amount of second-harmonic distortion, because only the difference of the errors introduced by the first and the second voltage-current converters 5 and 9 is of importance in this respect and these errors are substantially equal to each other due to the method of fabrication of the voltage-current converters.
