LOW OUTPUT IMPEDANCE RF AMPLIFIER |
摘要 |
A radio frequency (RF) power amplifier includes a low impedance pre- driver (513) driving the input of a common- source output amplifier stage (514). The preamplifier (513) includes a first transistor (502) that has a first terminal coupled to a preamplifier RF input node (501), a second terminal coupled to a preamplifier RF output node (503), and a third terminal coupled to a supply voltage node (515). A first inductor (504) is coupled between the RF output node (503) and a bias voltage node (505). A voltage difference between respective first and second voltages on the RF input node (501) and the RF output node (503) that are substantially in phase, determines current through the first transistor (502). |
