3.集成电路集成电路使用直流电源,包括数字电路与模拟电路两大类。直流电源功率容量应大于电子电路中所有元器件的静态功耗与动态功耗之和。电源电压不能超出集成电路的极限使用电压值,否则容易损坏器件,例如TTL电路采用5V正电源。所谓正电源是指采用正逻辑设计的器件,即5V为高电平,0V为低电平。PMOS电路一般采用-20V、-24V负电源。所谓负电
3. Integrated circuit IC using DC power supply, including digital circuits and analog circuits in two broad categories. DC power supply power capacity should be greater than the sum of the static power consumption and dynamic power consumption of all components in the electronic circuit. The supply voltage must not exceed the maximum operating voltage of the IC. Otherwise, the device may be damaged. For example, the TTL circuit uses a 5V positive supply. The so-called positive power refers to the use of positive logic device design, that is 5V high, 0V low. PMOS circuit generally use -20V, -24V negative power supply. The so-called negative electricity
