查询词典 operate

Thus, the output will always be driven by a single transistor, either P- channel or N-channel. Since they are as closely matched as possible, the output resistance of the gate will always be the same, and signal behavior is therefore more predictable. Fig. 3.4 CMOS NAND gate One of the main problems with CMOS gates is their speed. They cannot operate very quickly, because of their inherent input capacitance. B-series devices help to overcome these 24 Lesson 3 CMOS Logic Circuit 25 limitations to some extent, by providing uniform output current, and by switching output states more rapidly, even if the input signals are changing more slowly. Note that we haven't gone into all of the details of CMOS gate construction here. For example, to avoid damage caused by static electricity, different manufacturers developed a number of input protection circuits to prevent input voltages from becoming too high. [3] However, these protection circuits don't affect the logical behavior of the gates, so we won't go into the details here. New Words and Phrases 1. CMOS abbr.
