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 4):
The envelope tracking bias circuit of  claim 2 , wherein the ET VCC detection circuit comprises:\n a first attenuator connected to the first input terminal and configured to attenuate the ET operation voltage input through the first input terminal to be within a predetermined voltage range, and output the attenuated ET operation voltage; a first inverting amplification circuit configured to inversely amplify the attenuated ET operation voltage, and switch on and off an output of the inversely amplified attenuated ET operation voltage from the ET VCC detection circuit in response to a first VCC control signal of the VCC control signal; and a second non-inverting amplification circuit configured to non-inversely amplify the attenuated ET operation voltage, and switch on and off an output of the non-inversely amplified attenuated ET operation voltage from the ET VCC detection circuit in response to a second VCC control signal of the VCC control signal.
