Abstract:
An envelope tracking (ET) bias circuit includes a detection circuit configured to select an ET operation voltage input through a first input terminal of the detection circuit, or an envelope signal detected from a radio frequency (RF) signal input through a second input terminal of the detection circuit, in response to a first control signal, to and output he selected one of the ET operation voltage and the envelope signal as a detection signal; an amplification circuit configured to amplify the detection signal, and output the amplified detection signal; and a bias output circuit configured to generate an ET bias current based on the amplified signal, and output the generated ET bias current.

Claim (Index 9):
The power amplifying device of  claim 8 , wherein the detection circuit comprises:\n an ET VCC detection circuit configured to amplify the ET operation voltage input through the first input terminal, and output the amplified ET operation voltage in response to the VCC control signal of the first control signal; and an RF envelope detection circuit configured to detect an envelope of the RF signal input through the second input terminal, and output the envelope in response to the RF control signal of the first control signal.
