Publication number: 20100007324Abstract: The invention relates to a temperature-independent voltage reference circuit. The circuit comprises a first circuit of bandgap type providing a first-order temperature-stable voltage, on the basis of a bipolar transistor base-emitter voltage having a negative slope of variation as a function of temperature, and of a voltage or a current having a positive slope of variation as a function of temperature provided by a generator of current proportional to absolute temperature. The base currents of the PMOS transistors thereof are compensated in such a manner that the output current is proportional to a collector current and not an emitter current.Type: ApplicationFiled: October 5, 2007Publication date: January 14, 2010Applicant: E2V SEMICONDUCTORSInventors: Thierry Masson, Jean-Francois Debroux, Pierre Coquille

Patent number: 5530404Abstract: A variable gain amplifier which has n parallel-connected elementary amplifiers, and components for selecting j-order (j=1, 2, . . . , n) elementary amplifier according to the desired gain. Each elementary amplifier is of a common base type. The variable gain amplifier includes components that are used to obtain a low value input impedance that is independent of the gain of the selected elementary amplifier. The variable gain amplifier will find particular application at the input stages of amplification lines of receiving circuits which require noise performance characteristics.Type: GrantFiled: December 8, 1994Date of Patent: June 25, 1996Assignee: Thomson-CSF Semiconducteurs SpecifiquesInventor: Jean-Francois Debroux

Patent number: 5506525Abstract: A sampling circuit which obtains a level of sampled-and-held signal which is determined with respect to a well-determined reference level V0, even though the input signal is a useful signal referenced with respect to a low-stability reference level. This is the case in particular for sampling of signals derived from charge-transfer photosensitive devices for which the dark level can vary. The circuit includes a sample-and-hold device (EB1) and an input via a capacitor (C1), with a reset circuit which periodically charges the capacitor (C1) to a value which is roughly the difference between the (variable) input reference level and the (fixed) output reference level. According to the invention, it is provided that the reset circuit comprises a looped amplifier (AD1) in which the loop (B1, EB2, B2) is designed to introduce a voltage level shift equal to the shift introduced intrinsically by the sample-and-hold device (B1, EB1, B2).Type: GrantFiled: July 29, 1992Date of Patent: April 9, 1996Assignee: Thomson Composants Militaires Et SpatiauxInventor: Jean-francois Debroux

Patent number: 5376900Abstract: A push-pull output stage for electronic integrated circuits includes two NPN transistors (Q1, Q2) connected in series between two supply terminals. The output (S) is the junction point of the transistors. A third NPN transistor (Q3) has its base and its collector connected respectively to the base and to the collector of Q1. Two current flow arms (R1, Q4 and R2, Q5) are formed, one to establish a current depending on the potential of the emitter of Q3 and the other to establish a current depending on the potential of the emitter of Q1. The arms are mounted in a current mirror arrangement, the second arm tending to copy the current of the first arm; the current mirror generating a current output (S2) representing a difference between the current set up in the second arm and the current copied from the first arm. This current output is used to control the conduction of the second transistor (Q2).Type: GrantFiled: March 3, 1993Date of Patent: December 27, 1994Assignee: Thomson-CSF Semiconducteurs SpecifiquesInventor: Jean-Francois Debroux

Patent number: 5278518Abstract: The invention relates to an amplifying circuit with controlled gain, the gain of which is an exponential function of a gain control voltage. The circuit includes two identical amplifiers A1 and A2, the first constituting the basic amplifying cell of the circuit (input Ie, output Is), and the second receiving a reference signal (Iref). The output from the second amplifier, which is the product of the input Iref times the gain G, serves as input to a feedback control loop for the gain G of the amplifiers. This loop receives a set point voltage Vc with a view to establishing a gain G which is an exponential function of Vc. A large-gain differential amplifier AD constitutes the core of this loop: the differential voltage between its inputs tends to be held at zero by the feedback control loop. According to the invention, an element (FTL) with logarithmic transfer function is inserted into the loop between the output of the second amplifier A2 and the input of the large-gain differential amplifier AD.Type: GrantFiled: October 8, 1992Date of Patent: January 11, 1994Assignee: Thomson Composants Militaires et SpatiauxInventor: Jean-Francois Debroux

Patent number: 5034701Abstract: Disclosed is an amplifier circuit with gain controlled by a current or a voltage. It is sought to obtain a linear gain as a function of the set value current or voltage, whereas amplifiers with controlled gain usually have a non-linear variation of the gain as a function of gain control voltage. According to the invention, there is proposed an amplifier circuit with the particular feature of having two identical amplifiers with controlled gain: one receives the signal to be amplified and gives an amplified output signal; the other receives a reference voltage or current and gives an output which is compared with a signal with a set value of variation in gain. The result of the comparison is used to automatically control the gain of the second amplifier to adjust its output to a desired value. The first amplifier receives the same automatic control signal as the second one.Type: GrantFiled: March 28, 1990Date of Patent: July 23, 1991Assignee: Thomson Composants Militaires et SpatiauxInventor: Jean-Francois Debroux
