摘要： An integrated circuit for the transmission of telephone signals is designed so as to be inserted in a speech circuit of a subscriber's telephone set and includes a threshold comparator having first and second input terminals coupled to the terminals of a two-wire telephone line and an output terminal connected to a point of the signal path of the circuit. The threshold of this comparator is set such that when the voltage at the terminals of the line drops to a predetermined value, which is not lower than the minimum voltage value required to ensure the correct operation of all the components of the circuit, it generates an output signal used to limit the amplitude of the negative peaks of the waveforms of the transmitted signals.

摘要： A final bridge stage for a receiver audio amplifier, which can be monolithically integrated, consists of two pairs of complementary bipolar transistors. The collectors of the transistors of each of the transistor pairs are connected together to form two terminals to which a transducer is connected. The transistor emitters of NPN type and PNP type transistors are respectively connected to the negative pole and, through a constant current generator, to the positive pole of a supply voltage generator. The constant current generator consists of a small resistor to which a constant voltage is applied by means of a suitable circuit. The bases of the bridge transistors are connected to the signal source by means of suitable circuits. The signal source controls similar transistors in phase opposition, while at the same time controlling the complementary transistors in phase opposition.

摘要： Distortion control in a push-pull output stage of a speech amplifier of a telephone powered through the telephone line is more effectively and advantageously implemented by independently sensing an eventual state of saturation reached by any of the two output transistors of the amplifier, summing the current signals representative of the sensed state of saturation of either or both output transistors, integrating the resulting sum current signal to produce a DC signal and using the DC signal for activating an AGC loop. The DC signal indiscriminately accounts for any cause of saturation, though virtually representing the level of the amplified AC signal. Distortion may be controlled without penalizing output voltage swing and power consumption.

The control configuration selects the voltage reference being applied to the power supply/transmitter blocks.
