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 7):
The envelope tracking bias circuit of  claim 2 , wherein the RF envelope detection circuit comprises:\n a rectifying circuit comprising: a negative rectifying circuit configured to detect a negative envelope of the RF signal input through the second input terminal, and output the negative envelope; and a positive rectifying circuit configured to detect a positive envelope of the RF signal input through the second input terminal, and output the positive envelope; and a buffer circuit comprising: a first buffered switch circuit configured to buffer the negative envelope, and switch on and off an output of the buffered negative envelope from the RF envelope detection circuit in response to a first RF control signal of the RF control signal; and a second buffered switch circuit configured to buffer the positive envelope, and switch on and off an output of the buffered positive envelope from the RF envelope detection circuit in response to a second RF control signal of the RF control signal.
