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 19):
A bias circuit comprising:\n a detection circuit configured to receive a radio frequency (RF) signal and an operation voltage related to the RF signal, generate a time-varying signal based on the RF signal, and output the operation voltage or the time-varying signal as a detection signal in response to a VCC control signal and an RF control signal of a control signal; an amplification circuit configured to amplify the detection signal; and a bias output circuit configured to generate a bias signal based on the amplified detection signal.
