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 22):
The bias circuit of  claim 19 , wherein the RF signal is an RF input signal of a power amplifier or an RF output signal of the power amplifier;\n the operation voltage is an envelope tracking (ET) operation voltage of the power amplifier that tracks an envelope of the RF input signal or an envelope of the RF output signal; the time-varying signal is an envelope of the RF signal; and the bias output circuit is further configured to generate an ET bias signal as the bias signal based on the detection signal, and output the ET bias signal to the power amplifier as a bias signal of the power amplifier.
