摘要： An amplifier arrangement includes a first section and a second section. The second section has an output transistor which is protected by a protection circuit. The protection circuit acts on the input of the second section in order to obtain a higher gain in the protection loop. In order to preclude instabilities, the protection circuit has a falling frequency response with a flat portion in view of the frequency compensation of the second section.

摘要： A current-distribution circuit (1) supplies a plurality of substantially equal currents (i.sub.1, i.sub.2, i.sub.3 and i.sub.4) to a permutation circuit (13), which transfers these currents to outputs (18, 19, 20 and 21) in accordance with a cyclic permutation. The currents in these outputs exhibit a ripple caused by the inequality of the currents (i.sub.1, i.sub.2, i.sub.3 and i.sub.4). A detection circuit (30) detects the ripple component of the currents (i.sub.1, i.sub.2, i.sub.3 and i.sub.4) and applies this ripple component to a associated control circuit of a block of control circuits (50). The relevant control circuit supplies a control current for correcting the relevant current (i.sub.1, i.sub.2, i.sub.3 or i.sub.4) in such way that the ripple component is substantially eliminated.

摘要： The invention provides an improved class-B push-pull output stage comprising a first and a second output transistor of a first conductivity type, which stage is provided with a control loop for driving the second transistor in phase opposition as a function of the drive of the first transistor. Said control loop is adapted so that a stable quiescent-current setting is obtained and that the effect of poor high-frequency properties of a third transistor of a conductivity type opposite to the first conductivity type, which transistor is necessarily included in the control loop, is eliminated, so that a wide frequency range is obtained.

摘要： An analog-to-digital conversion circuit having a number of series-connected stages, each stage determining the difference between a signal current input and a reference current input, and at positive values of said difference transferring a current proportional to said difference to the succeeding stage. In each successive stage, the reference current is subtracted from the signal current until the residual current is smaller than the reference current. The number of successive stages in which this subtraction takes place can be detected to indicate the level of the input current. Each stage includes a common point for receiving the difference between the signal current and the reference current, a current path from said common point to its output for transferring a current proportional to the difference if positive, a current path from said common point to a current sink if said difference is negative; said current paths being unidirectional and biased such that only one is forward biased at one point in time. Each stage also detects the polarity of said difference to obtain a digital measure of the value of the signal current.
