摘要： A method and a circuit for correcting duty cycle distortion. A delay insertion gate corrects data dependent delay distortion that is generated by 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.

摘要： A torque driver that includes a regulator circuit for mitigating zero-g discontinuity effects and deadbanding is presented. An accelerometer may comprise the torque driver and the torque driver may be arranged to receive a control signal from a control circuit that is coupled to deflection sensing circuitry. When the accelerometer undergoes an acceleration the deflection sensing circuitry generates an acceleration signal that is communicated to the control circuit. The control circuit responsively generates a control signal, which the torque driver users 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.

摘要： Circuitry (100, 100') for determining actuator position includes four MOS transistors (T1-T4) connected to each side of a bi-directional motor (10). The current flowing through the motor (10) at any given time is proportional to voltages developed across the internal impedances of the transistors (T1-T4). The resulting motor voltages are amplified and high-pass filtered to remove any DC offsets due to the signal amplification. The conditioned motor voltages are then compared to one or more threshold voltages and passed through a one shot circuit (120) to provide detectable pulses for each motor commutation event. Circuitry (106,107) is provided for counting pulses provided by the one shot circuit (120) and, based on a desired motor position, for providing a number of digital control signals to a digital control circuit (104). Digital control circuit (104) is responsive to the number of digital control signals to control the gate voltages of the four transistors (T1-T4) to thereby control the position of the motor (10).

摘要： An electromechanical system (MEMS) voltmeter. An exemplary MEMS voltmeter includes a proof mass mounted to a substrate in a teeter-totter manner. The MEMS voltmeter also includes an input voltage plate located on the substrate under a first end of the proof mass. The first input voltage plate receives a voltage from a device under test. A drive voltage plate is located on the substrate under a second end of the proof mass. A first sense input voltage plate is located on the substrate under the first end of the proof mass. A second sense voltage plate is located on the substrate under the second end of the proof mass. A rebalancing circuit receives signals from the proof mass and the first and second sense voltage plates and generates a voltage value that is equal to the root mean square (RMS) voltage of the device under test.

摘要： This disclosure is directed to devices and integrated circuits for instrumentation amplifiers. 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 respective 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.

摘要： An improved motor commutation pulse detection circuit for comparing a filtered motor current signal to a threshold value, where the circuit is responsive to the actual or expected amplitude of the commutation pulses for adjusting the motor current signal or the threshold value so that the compared threshold value is substantially equal in amplitude to minimum amplitude commutation pulses in the compared motor current signal. In one circuit, the threshold value is varied in accordance with the average current flowing through the motor at the time of the commutation event. In another circuit, the threshold is effectively switched between a high value and a low value depending on the mode of operation of the motor. A motor run detection threshold is activated during motor running periods, while a motor brake detection threshold is activated during motor braking. The run time detection threshold is set to a relatively high value to detect the relatively high amplitude commutation pulses that occur during motor running, while the brake detection threshold is set to a relatively low value to detect the relatively low amplitude commutation pulses that occur during motor braking. The threshold can effectively be changed by attenuating the commutation signal by a predetermined factor during motor run periods.
