    Abstract: PROBLEM TO BE SOLVED: To provide a method and a circuit for correcting duty cycle distortion.
    SOLUTION: The present invention relates to the method and circuit for correcting duty cycle distortion. A delay insertion gate corrects data dependent delay distortion that is generated in CMOS flip-flop circuits. The delay insertion gate includes two field effect transistors and a current mirror. The two transistors each respectively receive an input signal from an upstream circuit. At least one of the transistors is coupled to an output node. The output node temporarily holds a voltage state within the delay insertion gate, correcting any distortion in the duty cycle of the input signals.

    Abstract: PROBLEM TO BE SOLVED: To provide a torque driver that includes a regulator circuit for mitigating zero-g discontinuity effects and deadbanding. SOLUTION: An accelerometer may include the torque driver and the torque driver may be arranged to receive a control signal from a control circuit that is coupled to a deflection sensing circuit. When the accelerometer undergoes an acceleration, the deflection sensing circuit generates an acceleration signal that is communicated to the control circuit. The control circuit responsively generates a control signal, which the torque driver uses to balance a proof mass beam within the accelerometer. The regulator circuit mitigates zero-g discontinuity effects and deadbanding by preventing the torque signal from producing torque signals that simultaneously track the control signal. To do this, the regulator circuit may include a rectifying buffer and/or a modulator. COPYRIGHT: (C)2008,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide devices and integrated circuits for instrumentation amplifiers.SOLUTION: In one example, an instrumentation amplifier device uses two non-inverted outputs of a first multiple-output transconductance amplifier, and a non-inverted output and an inverted output of a second multiple-output transconductance amplifier. Both multiple-output transconductance amplifiers have a non-inverted output connected to an inverting input, and a non-inverting input connected to a corresponding input voltage terminal. A first resistor is connected between the inverting inputs of both multiple-output transconductance amplifiers. The outputs of both multiple-output transconductance amplifiers are connected together, connected through a second resistor to ground, and connected to an output voltage terminal. In other examples, two pairs of outputs from triple-output transconductance amplifiers are connected to provide two voltage output terminals, and may also be connected to buffers or a differential amplifier. These provide various advantages over traditional instrumentation amplifiers.

    Abstract: PROBLEM TO BE SOLVED: To provide a temperature compensated low voltage reference circuit with a reduced operating voltage overhead. SOLUTION: This is accomplished in several ways including minimizing drain voltage variation at the drains of two inter-connected transistors and implementing a current conveyer in order to adjust the temperature coefficient of an output current or voltage. In one embodiment, a voltage reference circuit employs voltage regulating circuitry to reduce voltage differences caused by short channel effects. The reduction of these voltage differences allows for a lower overhead voltage. In a second embodiment, these voltage differences are reduced by regulating circuit nodes within the voltage reference circuit with a bipolar junction transistor (BJT) which have more ideal characteristics. In these two embodiments, the voltage reference circuit may be a band gap reference circuit or a sub-band gap reference circuit. COPYRIGHT: (C)2007,JPO&INPIT
