This requires an overall voltage gain of 109, so a number of voltage gain stages will be required.
这就要求电压的总增益达到109，因此就需要很多放大器级联起来。
Many practical amplifiers chain together a series of analog amplifier stages to obtain a high overall voltage gain.
许多实际的放大器将多个放大器级联起来，以获得较高的电压增益。
This situation can arise, for example, when a transconductance amplifier feeds an output current i0 to a load resistor RL, but the overall circuit is considered to give a voltage gain VL/Vi.
例如当一个互导放大器提供一输出电流i0到负载电阻RL，而全部网络给出电压增益为VL/Vi时，就可出现这种情况。
