The earlier estimate showed that the cascode output resistance is very large. The implication is that many load resistances will not satisfy the condition "RL Â» Rout" (an important exception is driving a MOSFET as the load, which has infinite low frequency input impedance). However, the failure to satisfy the condition "RL Â» Rout" is not catastrophic because the cascode gain also is very large. If the designer is willing, the large gain can be sacrificed to allow a low load resistance; for "RL" Â« "Rout" the gain simplifies as follows:
