    Abstract: A sense circuit for reading EPROM and ROM type memory cells employs a circuit for generating an offsetting current which is exempt of error during transients and which thus permits to achieve a reduced access time. On the other hand, the sense circuit maintains the intrinsic advantages of a current-offset sensing architecture which is represented by a substantially unlimited operating voltage range toward the maximum value VCC.sub.max. The current generating circuit is driven by means of a supplementary row of cells which is decoded at every reading and which replicates, during transients, the behaviour of the row selected for the reading.

    Abstract: The power output of a static DC--DC converter employing a current mode PWM controller is controlled upon the varying of the switching frequency, by detecting the sawtooth signal produced by the local oscillator generating a DC signal with an amplitude inversely proportional to the frequency. The power output is controlled by alternatively clamping the output voltage of the error amplifier of the PWM controller at a voltage proportional to the amplitude of the DC signal, or by offsetting the signal present on the current sensing resistor by a voltage corresponding to the difference between a constant voltage and the DC signal.

    Abstract: A method of depositing a layered dielectric structure to improve the planarity of electronic devices which include a plurality of active elements having gate regions laid across the substrate as discrete parallel lines, such as the bit lines of memory cells. The bit lines are isolated from one another by a layered dielectric structure to provide a planar architecture onto which an optional conductive layer may be deposited. The dielectric structure is formed from a highly planarizing dielectric layer of the SOG type spun over a first insulating dielectric layer and solidified by means of a thermal polymerization process. After solidifying the dielectric layer, it is subjected to a rapid thermal annealing treatment.

    Abstract: The circuit of a two-stage fully differential amplifier includes a differential input stage, two output stages and a common mode feedback circuit coupled to the output nodes of the amplifier. The amplifier also includes a non-inverting stage coupled to a respective output node of the differential input stage for driving the respective output stage. Each auxiliary non-inverting stage of the two branches of the fully differential amplifier uses as a biasing current generator, the load device of the branch of the differential input stage to the output of which the non-inverting stage is coupled. The fully differential amplifier permits the use of a null-consumption common mode feedback circuit as normally employed only in a single stage fully differential amplifier.
