  • Isolated output switching circuit
    Patent number: 9893724
    Abstract: A semiconductor device includes an output switching device having an input node, an output node, and a control input node. The control input node enables an input voltage applied to the input node to be switched to the output node. A gate pull-down circuit controls the control input node of the output switching device in response to at least one control signal. The gate pull-down circuit activates the output switching device by raising the voltage level of the control input node above the voltage level of the output node and deactivates the output switching device by clamping the control input node to the voltage level of the output node. A gate pull-up circuit receives an enable signal and generates the at least one control signal to the gate pull-down circuit in response to the enable signal.

  • Target specific folded analog to digital converter for direct access storage device (DASD)
    Patent number: 6157336
    Abstract: A target specific folded analog to digital converter (ADC) is provided, such as for use in a data detection channel in a direct access storage device (DASD). The high speed analog to digital converter (ADC) includes a digital signal decoder for decoding specific target levels of an analog signal. An analog to digital converter section of the ADC converts an analog error signal of the analog signal to digital decoder outputs representing the analog error signal.
