—Recent progress of wide-band communication systems demands high-frequency circuits. Conventionally, the linearity of the operational transconductance amplifier and ca-pacitor (OTA-C) has been analyzed using Taylor series expansion. Unfortunately, this approach does not predict the frequency-dependent linearity degradation. Thus, to properly design(More)
The Faith-Menal conjecture says that every strongly right Johns ring is QF. The conjecture is also equivalent to say every right noether-ian left F P-injective ring is QF. In this short article, we show that the conjecture is true under the condition(a proper generalization of left CS condition) that every nonzero complement left ideal is not small(a left(More)
Hazard and operability (HAZOP) methodology is an important Process Hazard Analysis (PHA) technique for ensuring safety production in chemical industry. Due to the lacks of accuracy and reliability in manual HAZOP analysis, the quantitative HAZOP analysis has gained more and more attention. In this work, a process simulation-based HAZOP analysis method and(More)
