In this paper, a gain-boosting preamplifier-latch comparator with minimum input referred offset voltage is proposed. The preamplifier utilizes telescope structure with cross-coupled active loading, which enhances the gain of preamplifier. In order to minimize the delay time of comparator, the input DC range and the ratio of PMOS/NMOS are selected carefully. The circuit is fabricated in TSMC 0.18um...
Currently, the virtualization technologies can integrate multiple operating systems into a high-performance server to maximize the utilization of the server's resources. This server can serves more users. However, the driver faults in virtual machine still seriously affect the reliability of the virtual machine, and even affect the reliability of the entire server. This paper presents Chariot, a high...
Driver faults are the main reasons of causing failure in operating system. In order to address this issue and improve the kernel reliability, this paper presents an intelligent kernel-mode driver enhancement mechanism - Style Box which can limit the driver's rights to access kernel by a private page table and a call control list. This method captures a variety of type errors, synchronization errors...
