饱和逻辑电路saturated logic circuit 这是以晶体管的截止状态(即关闭状态,电流很小)和饱和状态(即通导状态,电流最大)对应于逻辑电路的两个状态(“0”和“1”)而构成的电路。具有电平稳定、电路结构简单、功耗低等优点,但其开关速度比非饱和逻辑电路慢。非饱和逻辑电路unsaturated logic circuit 这种数字电路是以晶体管有效工作区(即晶体管既不截止也不饱和的状态)中的两个值(高电平、低电平),分别对应于逻辑的两种状态

Saturated logic circuit This is the logic state of the transistor (ie, closed state, the current is small) and saturation state (conduction state, the largest current) corresponds to the two states of the logic circuit (“0” and “1” ) And constitute the circuit. With the advantages of stable level, simple circuit structure and low power consumption, the switching speed is slower than non-saturated logic circuit. Unsaturated logic circuit This kind of digital circuit is based on two values ​​(high level, low level) in the effective working area of ​​the transistor (that is, the state of the transistor is neither cut-off nor saturation), corresponding to two logic Kind of status
