Abstract
A driving amplifier with low output impedance is disclosed. In one aspect, a driving amplifier stage that does not need an inter-stage impedance matching network between the driving amplifier stage and an output amplifier stage in a transmission chain may be achieved by providing stacking transconductance devices within the driving amplifier stage and reusing a supply current to provide an intermediate signal with high current but moderated voltage swing to drive the output amplifier stage. In specifically contemplated aspects, the stacked transconductance devices may be complementary metal oxide semiconductor (CMOS) field effect transistors (FETs).
