This paper presents an ultra-low power operational transconductance amplifier (OTA) operating in the weak inversion region. To increase dc gain, this OTA includes two partial positive feedbacks input differential pair and active loads. In addition, we output resistance by increasing channel length L of transistors. analyze stability OTA, transfer function as well small-signal voltage are derive...

Model stealing attacks have been successfully used in many machine learning domains, but there is little understanding of how these work against models that perform malware detection. Malware detection and, general, security domains unique conditions. In particular, are very strong requirements for low false positive rates (FPR). Antivirus products (AVs) use complex systems to steal, binaries c...
