    Abstract: A bipolar transistor, comprising a collector region, a base region, and an emitter region, is a type which is compatible to CMOS processes leading to the formation, on a semiconductor substrate, of N-channel and P-channel MOS transistors having respective source and drain regions. In such bipolar transistor, the collector region is a substrate diffused pocket and the base region is formed within the diffused pocket simultaneously with the source and drain regions of the P-channel MOS transistors. Further, the emitter region is incorporated, in turn, to the base region simultaneously with the source and drain regions of the N-channel MOS transistors.

    Abstract: A circuit for regulating the charging voltage to a battery and connected to the field inductor (IND) of an alternator (ALT) which supplies that voltage. It is connected by a control cable to the battery and comprises an electric path, extending between a terminal for connection to the alternator and ground, which is only activated when the battery voltage drops below a predetermined threshold value. This electric path comprises a switch (TSW) driven from a control circuit (COMP1,T4) which sense the battery voltage, and when activated, the voltage drop across the path is substantially equal to that of the regulated voltage. The control circuit also senses breakage in the battery sensing cable, and ceases driving the alternator when this occurs.

    Abstract: A pulse generator has an input and two outputs at which to respectively generate pulses in relation to different types of signal edges received at the input of the generator. The generator provides two distinct logic circuit blocks of the sequential type, the blocks being mutually independent for generation of the pulses at the two outputs. In this manner it is possible to easily control the characteristics of the pulses. In addition, if two blocks are connected with appropriate and simple logic networks, it is possible in the generation phase to impose conditions between the pulses at the two outputs in a simple manner and with a certain freedom.

    Abstract: A differential charge pump circuit employing a lowpass filter network which is chargeable and dischargeable by switchingly controlled current generators. The differential charge pump employs two identical current generators for injecting the same current I in a substantially continuous manner, on the two significant nodes of the lowpass filter. The differential charge pump also employs two pairs of identical, switchingly controlled current generators connected to the two significant nodes, respectively, each capable of pulling a current I. The two generators forming each of the two pairs of switchingly controlled current generators are controlled by one of a pair of control signals (UP, DOWN) and by the inverted signal of the other of the pair of control signals, respectively. All four switchingly controlled generators may be of the same type (N-type), thus ensuring high speed and precision. The two identical (P-type) current generators employed for continuously injecting the same current I on the two nodes of the lowpass filter may be controlled through a common mode feedback loop for enhanced precision.
