摘要： Various pipeline ADCs are disclosed that substantially compensate for interference or distortion that results from imperfections with various ADC modules of the pipeline ADCs. The pipeline ADCs include various ADC stages and various compensation stages that are coupled to the various ADC stages. The various ADC stages convert their corresponding analog inputs from an analog signal domain to a digital signal domain to provide various digital output signals and various analog residual signals to subsequent ADC stages. The various compensation stages compensate for interference or distortion that is impressed onto the various analog residual signals which results from imperfections within previous ADC stages.

摘要： A line driver comprises a driving amplifier receiving an input of the line driver, a current sense resistor connected between the driving amplifier output and the line driver output, and a feedback amplifier sensing the voltage across the current sense resistor and providing a corresponding feedback voltage that is proportional to the output current to the driving amplifier, thereby determining an output impedance at the line driver output. Precise output impedance can be realized by using a high precision resistor as the current sense resistor, and using resistive feedback amplifiers with accurate gains as the driving and feedback amplifiers. The resistance of the current sense resistor can be substantially less than the line driver output impedance, and the driving amplifier output voltage swing can be substantially less than twice the line driver output voltage swing.

摘要： Apparatuses, methods, and systems for effective power management distribution are provided. In an embodiment, a system for providing power to a circuit block comprises a power management unit (PMU) configured on a first substrate and an integrated circuit (IC) configured on a second substrate. The PMU includes a first regulator configured to step down an input voltage and output a first regulated voltage. The IC includes the circuit block and a second regulator configured to receive the first regulated voltage and output a second regulated voltage. The second power regulated voltage provides power to the circuit block. The first regulator is more efficient than the second regulator.

摘要： Disclosed is a hydraulic damper comprising a rotor (1), a stator (2) and a drive shaft (3) for driving the rotor (1), the rotor (1) and the stator (2) being mutually forming a working chamber (4) in which liquid medium is accommodated, wherein the stator (2) is provided in turn with an outlet (21), a nozzle (22), an exhaust channel (23), an ejector channel (24) and an inlet (25); the outlet (21), the exhaust channel (23) and the inlet (25) are communicated with the working chamber (4) respectively; the ejector channel (24) is in communication with the outlet (21), the exhaust channel (23) and the inlet (25) respectively; the nozzle (22) is arranged at the junction where the outlet (21) is connected with the exhaust channel (23) and the ejector channel (24); the nozzle (22) is extended along the lead-out direction of the outlet (21) to the junction where the exhaust channel (23) is connected with the ejector channel (24), and the channel width of the nozzle (22) at the extension is smaller than that of the outlet (21) and that of the ejector channel (24) respectively. With the Bernoulli's principle, hydraulic damper proposed in the present application can effectively avoid the loss of the liquid medium in the working chamber (4).
