An isolation member having an isolation channel is located between the first tube and the second tube. The isolation member obstructs the heat exchange between the first tube and the second tube. A first delivery tube and a second delivery tube of each one of the heat-conductive bodies respectively connect to the first tube and the second tube of the heat-conductive tube, thereby integrating the first tube and the second tube and obstructing the heat exchange between the cooling liquids with different temperatures. Each of the heat-conductive units distributes the cooling liquids with different temperatures by the heat-conductive tube, thereby simplifying the pipeline setting and reducing the volume of the liquid-cooling heat sink.

A digital down converter with an equalizer translates an ADC output signal to a low frequency spectral region, followed by decimation. All operations of correction of the processed signal are carried out with a reduced sampling rate compared with sampling rates of the prior art.

The achieved reduction of the required computation resources is sufficient to enable the down converter with equalization to operate in a real time mode.

Input device adhesive techniques are described. A pressure sensitive key includes a sensor substrate having one or more conductors, a spacer layer, and a flexible contact layer. The spacer layer is disposed proximal to the sensor substrate and has at least one opening. The flexible contact layer is spaced apart from the sensor substrate by the spacer layer and configured to flex through the opening in response to an applied pressure to initiate an input. The flexible contact layer is secured to the spacer layer such that at first edge, the flexible contact layer is secured to the spacer layer at an approximate midpoint of the first edge and is not secured to the spacer along another portion of the first edge and at a second edge, the flexible contact layer is not secured to the spacer layer along an approximate midpoint of the second edge.

Typically, complex systems require a separate and expensive equalizer at the output of an analog-to-digital converter (ADC). Rather than providing a separate equalizer, the effective Signal Transfer Function (STF) of a Multi-stAge noise SHaping (MASH) ADC can be modified by leveraging available digital filtering hardware necessary for quantization noise cancellation. The modification can involves adding calculations in the software previously provided for computing digital quantization noise cancellation filter coefficients, where the calculations are added to take into account equalization as well. As a result, the signal transfer function can be modified to meet ADC or system-level signal-chain specifications without additional equalization hardware. The method is especially attractive for high-speed applications where magnitude and phase responses are more challenging to meet.

For continuous-time multi-stage noise shaping analog-to-digital converters (CT MASH ADCs), quantization noise cancellation often requires accurate estimation of transfer functions, e.g., a noise transfer function of the front end modulator and a signal transfer function of the back end modulator. To provide quantization noise cancellation, digital quantization noise cancellation filters adaptively tracks transfer function variations due to integrator gain errors, flash-to-DAC timing errors, as well as the inter-stage gain and timing errors. Tracking the transfer functions is performed through the direct cross-correlation between the injected maximum length linear feedback shift registers (LFSR) sequence and modulator outputs and then corrects these non-ideal effects by accurately modeling the transfer functions with programmable finite impulse response (PFIR) filters.

A flash analog-to-digital converter (ADC) includes comparators that convert an analog input signal to a digital output signal. Offsets of these comparators introduce noise and can hurt the performance of the ADC. Thus, these comparators are calibrated using calibration codes. Conventional calibration methods determine these calibration codes by removing the ADC from an input signal. Otherwise, it is difficult to distinguish the noise from the signal in the calibration measurement. In contrast, an embodiment can determine the calibration codes while the ADC converts the input signal to a digital signal. Such an embodiment can be achieved by a frequency-domain technique. In an embodiment employing a frequency-domain power meter, an input signal can be removed from the power measurement. This removal enables accurate measurement of in-band noise without having the measurement be corrupted by input signal power.

A probabilistic digitizer for extracting information from a Josephson comparator is disclosed. The digitizer uses statistical methods to aggregate over a set of comparator readouts, effectively increasing the sensitivity of the comparator even when an input signal falls within the comparator's gray zone.
