摘要： A sigma-delta modulator of second or higher order includes two or more integrating stages, and a comparator connected in cascade to the integration stages. A signal having a logic level +1 is generated when an input signal to the sigma-delta modulator is positive, and a signal having a logic value −1 is generated when the input signal is negative. Regardless of its absolute value, a feedback line includes a low-pass filter and an adder circuit for adding a feedback signal. The signal output by the last of the integrating stages is filtered by the low-pass filter. The sigma-delta modulator further includes a second comparator having an input connected in common to the input of the first comparator and an output connected to an input of the low-pass filter. The second comparator outputs a logic signal having a positive value when the input signal is positive, and outputs a logic signal having a negative value when the input signal is negative. The second comparator also outputs a signal having an increasing logic level when the input signal exceeds one or more predefined thresholds of increasing value.

摘要： A digital circuit generates a phase synchronization signal for a digital input signal coded according to a biphase modulation. The phase synchronization signal is derived from a clock signal having a higher frequency than the maximum switching frequency of the digital input signal. The frequency of the clock signal is divided with a fully digital divider circuit having a non-integer ratio. The divider is self-synchronizing with the input digital signal. Control signals are used to enable or disable switching of the frequency divider. These control signals are generated by two circuits which sample the input signal with the master clock signal and analyze triplets of consecutive sampling values.

摘要： Generation of symmetrical temperature compensated reference voltages in mixed type integrated circuits (digital and analog) having a superior PSRR is provided. Such a circuit includes a voltage-to-current conversion stage of a temperature independent bandgap voltage for producing a differential pair of currents that are applied as inputs to a pair of resistor feedback operational amplifiers. The feedback resistors are integrated in an interlaced form with a resistor employed in the conversion stage so that they have the same thermal gradient. Output of the operational amplifiers provides two temperature compensated low noise symmetrical reference voltages.

摘要： A switched capacitor integrator particularly suitable to realize low-pass filters without inducing noise on the nodes of the reference potentials of the integrator, is provided by halving the input capacitance during an operating phase, and by transferring the electric charge between the input switched capacitance and the capacitor of integration of one and the other feedback branch of the differential amplifier, in a direct manner, that is, not referred to a fixed common potential. A unique current path is established, thus averting the effects caused by inevitable mismatches between the integrated capacitors.

摘要： Methods allowing precise directional drilling are provided. Such methods include use of directional drilling equipment which include a drill string with a hollow bottom rod connected to a boring tool by means of an obtuse-angle connection piece or “bent sub”. In order to restore the verticality of the drilling a vertical borehole section (F) is formed and then a probe equipped with an inclinometer is lowered inside the bottom rod. The string may be rotated into four angular positions and the inclination values of the probe in each angular position are detected at the depth reached. The string is rotated so as to bring it into an angular position corresponding to the maximum inclination value detected. The string is moved so as to move the boring tool further downwards and the inclination of the probe is detected again in order to check that verticality has been reached.
