Abstract: An integrated circuit device includes a first rectangular wave signal generation section that outputs a first rectangular wave signal when an amplitude of an oscillation signal inputted is greater than a first amplitude, and a second rectangular wave signal generation section that outputs a second rectangular wave signal when the amplitude of the oscillation signal is greater than a second amplitude that is greater than the first amplitude, and that controls the power supply voltage of an oscillation circuit by the first and second rectangular wave signals so as to maintain an appropriate potential difference with respect to a stop voltage against changes in the oscillation stop voltage associated with changes in a temperature condition.

Abstract: A Method and an apparatus for distributing a clock signal are disclosed. The apparatus for distributing a clock signal includes a pair of flat plates, a variable inductor and a connection channel. The pair of flat plates includes a clock flat plate having at least one of clock signal extraction points and a reference flat plate arranged in parallel to the clock flat plate. The inductor is connected between the pair of flat plates, and the connection channel is configured to connect electrically the at least one of clock signal extraction points to an external circuit. The inductor may be adjusted to have an inductance for generating a resonance signal of a target frequency from the pair of flat plates.

Abstract: Power savings are achieved for digital data transport over short distances by using the characteristics of resonant LC circuits. Economy of circuit elements is achieved by enabling a single pair of resonant circuits to drive large numbers of digital data lines or nodes in parallel. This maximizes power efficiency and minimizes area and cost. Resistance is minimized by insuring that all switches in the current path are fully “ON” whenever significant current is flowing through them. All other parasitic resistances in the circuits, consisting primarily of parasitic interconnect resistances, are minimized. This enables the data transmission circuits to achieve maximum Q or quality factor, which minimizes power dissipation.

Abstract: A power-diode driver uses a single power source to supply power to the sub-drivers inside. The sub-drivers are well isolated so that they can be safely and easily expanded by connecting to other device or driver. Thus, the power-diode driver has a changeable turn-on time and a highly modulated assembly. And, hence, the present invention is suitable for mass producing reliable power-diode drivers.

Abstract: Circuits for the restoration of a drooped signal are disclosed. In the asynchronous mode circuit, the drooped signal can be restored by detecting the peak of the positive amplitude and the peak of the negative amplitude and take the difference between the two peaks. This difference signal is fed back the equalizer. In the synchronous mode circuit, the drooped signal is sliced and passed to a regeneration circuit. The regeneration circuit uses reference voltage signals and phase information from the slicer to generate a regenerated signal. The regenerated signal is compared with the equalized signal to generate a difference signal, again fed back to the equalizer. The sliced signal is also fed to a clock recovery circuit which recovers the clock signal embedded in the received signal. The two circuits can be combined to provide an optimal circuit for the restoration of a drooped signal.

In one embodiment, a resonant inverter circuit includes first and second switching elements with first and second freewheeling diodes coupled across the respective switching elements. A first inductive bias element is coupled to the first switching element and a second inductive bias element is coupled to the second switching element. The first and second bias elements are inductively coupled with a resonant inductive element for biasing the respective first and second switching elements against avalanche current flow.

Abstract: Direct voltage and alternating voltage signals are decoupled from a first and a second pair of leads. The pairs of leads each carry an alternating voltage signal and they are subject to a direct voltage between them. A capacitive connection of the leads with the inputs of a signal receiving device allows decoupling of the alternative voltage signal. For decoupling one pole of the direct voltage signal, diodes are provided that are connected to the leads of the respective pair of leads. The diodes are each connected via a respective current source transistor to one terminal for the pole of the direct voltage. The control terminals of the current source transistors are controlled by the center tap of a voltage divider connected between the diodes. The embodiment for direct voltage decoupling is readily integratable.

Abstract: A device for generating a control signal voltage which is dependent on a resistance value of a variable resistor (8) includes a transformer (24) having a first winding (22) which is in series with the variable resistor and a rectifier diode (20). A current generator (32) coupled to a power source is coupled to a second winding (26) of the transformer and supplies it with a periodically interrupted current (I.sub.2). Upon each such interruption an exponentially decreasing current will flow through the first winding and also through the variable resistor (8). The peak value of the voltage drop produced by such current across that resistor is proportional to the resistance value thereof. It is also produced across the first winding (22) and is detected by the peak detector (62). That constitutes the control voltage (U.sub.c). Since the variable resistor is fully electrically isolated from the power source, it can be safely touched without shock hazard.

Abstract: In order to sample high-frequency signals, it is necessary to have a needle pulse train and a needle pulse train which is inverted with respect thereto. By means of a switch (T) which is controlled by a clock signal (U), a positive operating voltage (U.sub.B+) is applied for a limited period of time to a first conductor (L.sub.1) and a negative operating voltage (U.sub.B-) is applied for a limited period of time to a second conductor (L.sub.2). The two conductors (L.sub.1, L.sub.2) are connected via a respective diode (D.sub.1, D.sub.2), which are biased differently, to a respective resistor (RV.sub.1, RV.sub.2), which is connected to ground, and to a respective capacitor (C.sub.1, C.sub.2). The respective capacitors connected to a respective further resistors (RL.sub.1, RL.sub.2), which is connected to ground, the needle pulse train being present at one resistor and the needle pulse train which is inverted with respect to the first being present at the other resistor.

Abstract: An adaptive threshold circuit for use with a magnetic type of sensor that has a pick-up coil. The pick-up coil has an alternating voltage induced therein when a slot or tooth formed in a wheel rotates past the sensor. The circuit produces a square wave pulse voltage during positive half-cycles of the voltage generated in the pick-up coil. The circuit includes a digital to analog converter the input of which is connected to a selectable pulse counter. The pulse counter has a decrement function that allows for the count to be varied so as to accommodate sudden wheel decelerations. According to one embodiment, the counter may down count to reduce the count number. In accordance with a second embodiment, the counter may shift out one bit to perform a divide-by-two operation on the count number.
