    摘要: In an apparatus and method for monitoring defects in wafers, a monitoring circuit is fabricated on an area of each one of the wafers. The monitoring circuit includes representative devices that replicate similar devices located in a die area of the wafers. Defects if present in the representative devices contribute to a generation of a noise, thereby causing an imbalance in a differential signal measurable across selected ones of the representative devices. A digitizing circuit that uses a common mode voltage as a reference to measure the imbalance digitizes the differential signal to a digital signal, the digital signal being indicative of the noise generated by the defects. The digital signal is stored over a configurable time interval to form a digital bit stream. The digital bit stream is compared to a reference to determine whether the defeats are within an allowable range.

    摘要: A load current compensating output buffer circuit and method are disclosed. The circuit includes a buffer amplifier coupled to a supply voltage and the inverting input receives an input voltage and the non-inverting input couples to an output capacitive load. A feedback impedance with a variable resistance circuit and a Miller capacitance in series is coupled to an output of the buffer amplifier and the capacitive load. A pass transistor couples to the supply voltage and the output capacitive load, the pass transistor having a gate terminal coupled to the output of the output buffer amplifier and the feedback impedance, a load current passing through the pass transistor. A sense circuit is configured to sense the load current and apply a control voltage to the variable resistance circuit to vary the resistance of the variable resistance circuit based on the load current.

    摘要: For high speed amplifiers, the parasitic capacitances from the differential input pair introduce a zero that can affect performance. Here, a neutralization network has been provided that compensates for this zero by shifting its position. This is generally accomplished by using a pair of capacitors that are cross-coupled across the differential input pair of the amplifier.

    摘要: Systems and methods are provided for renting a peripheral storage entity to a remote client. From the service provider's vantage, one method transceives negotiation signals between a remote first client (the user) and a service provider, via a network link. Using the negotiation signals, the service provider agrees to rent a peripheral storage entity to the first client, and sends digital content from the peripheral storage entity via the network link to the remote first client. The peripheral storage entity may be located with the service provider or with a remote second client. System and methods are also provided from the perspective of remote clients that are either receiving or supplying peripheral storage entity content.

    摘要: A method and corresponding apparatus are provided. In operation, an analog signal is integrated with an integrator to generate an integrated analog signal. The integrated analog signal is compared, in synchronization with a first clock signal and a second clock signal, to a reference voltage with a plurality of comparators to generate a comparator output signal. A feedback current is then generated, in synchronization with the second clock signal, from the comparator output signal. The feedback current is fed back to at least one of the comparators, and the comparator output signal is latched in synchronization with the first clock signal to generate a latched output signal. This latched output signal is converted to a feedback analog signal, and a difference between the analog signal and the feedback analog signal is determined.
