    Abstract: The analog processor of this invention is programmable and capable of storing the processing coefficients in analog form. It comprises a storage section (MEM) having at least one output, plural outputs in most cases, and being adapted to respectively generate programming signals (PP) on such outputs; the storage section (MEM) is input a plurality of supply voltage signals (VI) and is operative to produce, in connection with information stored therein, one of the supply voltage signals on each of the outputs, it being understood that one voltage signal may be produced on several such outputs. Advantageously, the processor can also be programmed in a simple manner from circuits of the digital type if switches (SW) controlled by storage elements (E) are used in the storage section (MEM).

    Abstract: The analog processor of this invention can carry out processings independently of the operating temperature and process parameters, in a reliable manner and at high performance levels using fairly simple circuitry. To achieve this independence, the processor is basically implemented and integrated with MOS transistors, has both voltage inputs (AI) and outputs (OUT), and includes a biasing section (BIAS) which supplies voltage bias signals (VG), of which at least one is substantially the sum of a voltage proportional to the threshold voltage of the MOS transistors and a reference voltage. This reference voltage can be extracted from a reference potential which is stable to temperature and process parameters, for example that produced by a bandgap type of generator. A major feature of the processor according to the invention is the linearity of its input-output characteristic relative to that reference voltage. It follows that it may be advantageous to extract that reference voltage by division from a signal indicating the width of the input signal variation range, thereby to achieve compensation for or independence of variations of this range.

    Abstract: The present level shift circuit has a first (I1) and a second (I2) input respectively for input of a first and a second voltage signal and an output (OT) and comprises: a) a first transistor (Q1) having a control terminal (G1), a first (S1) and a second (D1) main conduction terminal identifying a main conduction path, and b) a second transistor (Q2) of the same type as said first transistor (Q1) and having a control terminal (G2), a first (S2) and a second (D2) main conduction terminal identifying a main conduction path. The first signal is applied essentially between said control terminal (G1) and said first terminal (S1) of said first transistor (Q1) and said second input (I2) is coupled with the control terminal (G2) of said second transistor (Q2). The currents flowing in the conduction paths of the first (Q1) and the second (Q2) transistors are mutually proportional and one made from the other. The output (OT) is coupled with the first terminal (S2) of the second transistor (Q2). The control terminal (G1) of said first transistor (Q1) is connected to a potential reference (GND). The first signal is applied essentially to said first terminal (S1) of said first transistor (Q1).
