POWER EFFICIENT AMPLIFIER |
摘要 |
<p>In one embodiment, an amplifier to drive a load in response to an input voltage signal, the amplifier including a first amplifier to drive the load, a second amplifier, and a control sub-circuit to put the second amplifier into an active mode to drive the load when the output voltage of the first amplifier falls outside a voltage window, and to put the second amplifier into an inactive mode when the output voltage of the first amplifier falls within the voltage window. An embodiment also includes a switch to de-couple a capacitive impedance from the load after the second amplifier is put into its active mode, and to couple the capacitive impedance to the load when the output voltage of the first amplifier falls within the voltage window. Other embodiments are described and claimed.</p> |
