摘要： The load of the cascode amplifier is varied by connecting another (secondary) load in parallel with the original load. The secondary load is connected through a MOSFET switch. During the High Gain Mode the MOSFET switch is OFF and the secondary load is electrically isolated from the main load, whereas in the Low Gain Mode the switch is turned ON and the secondary load appears across the primary load, reducing the effective load impedance. The secondary load is AC coupled such that the DC bias current does not pass through the secondary load and hence the Noise Figure (NF) and linearity (IIP3) performance are better in the Low Gain Mode. A number of such switchable loads can be connected across the load to obtain programmability.
摘要翻译： 通过将另一个（次级）负载与原始负载并联连接来改变共源共栅放大器的负载。 次级负载通过MOSFET开关连接。 在高增益模式期间，MOSFET开关为OFF，次级负载与主负载电隔离，而在低增益模式下，开关导通，次级负载跨越主负载，降低有效负载阻抗。 次级负载是交流耦合的，使得DC偏置电流不通过次级负载，因此低增益模式下的噪声系数（NF）和线性度（IIP3）性能更好。 可以跨负载连接多个这种可切换负载以获得可编程性。
