Patent number: 6678377Abstract: The invention relates to a monolithically integrated telephone circuit for driving wide-band telephone lines and transmitting digital data at a very high frequency. The telephone circuit is powered from a battery DC supply providing a pair of voltage references. The telephone circuit includes an output circuit portion including a pair of differential output stages, each having a pair of inputs and being connected with its output to a respective lead of a two-wire telephone line. The telephone circuit also includes a device for deriving a reference voltage from the supply voltage, and includes a low-voltage supply network which is input a DC signal and produces a voltage reference to be added to the reference voltage for delivery to one input of each output stage. The other input of each stage receives an AC signal in order to present at the circuit output a suitable AC+DC differential voltage for driving the telephone line.Type: GrantFiled: December 30, 1999Date of Patent: January 13, 2004Assignee: STMicroelectronics S.r.l.Inventors: Mauro Pasetti, Carlo Maria Milanese

Patent number: 4720852Abstract: A telephone circuit which may be monolithically integrated for generating control signals for displaying the telephone charges to a subscriber is coupled to an AC voltage signal generator of having a predetermined amplitude and frequency which are constant over time. The circuit includes a voltage generator for generating signals which are spaced over time and have a trapezoidal pulse waveshape. A multiplier circuit calculates the product of the signals supplied from the two voltage generators and supplies a signal which is sent to the speech circuit of the subscriber's line and is added to the speech signals. The trapezoidal pulse generator has a capacitor which is charged and discharged by a voltage to current converter of a non-linear type which is driven by exchange control components. The voltage across this capacitor forms the trapezoidal signals supplied by the generator.Type: GrantFiled: June 19, 1985Date of Patent: January 19, 1988Assignee: SGS Microelettronica SpAInventors: Marco Siligoni, Mauro Pasetti
