Title:
BOOST AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2020/246864
Kind Code:
A1
Abstract:
According to an embodiment of the disclosure, provided is an apparatus comprising a DC voltage source configured to output a DC supply voltage; and an amplifier comprising at least one DC/DC convertor operated by the DC voltage source, wherein the amplifier is configured to: receive an input signal; and generate, via the at least one DC/DC converter, an output signal by amplifying the input signal, wherein a output voltage level of the output signal covers from a voltage level lower than a DC supply voltage level of the DC supply voltage to a voltage level higher than the DC supply voltage level, wherein a gain of the amplifier is a ratio of the output voltage level to a voltage level of the input signal; and wherein a steady-state operating point of the at least one DC/DC converter is zero output.
