Abstract:
An envelope tracking (ET) current bias circuit includes a rectifying circuit, a phase compensation circuit, and a voltage/current conversion circuit. The rectifying circuit is configured to detect an envelope voltage from a radio frequency (RF) signal. The phase compensation circuit is configured to compensate for a phase of the envelope voltage in which the phase thereof is delayed in the rectifying circuit to output a phase compensated enveloped voltage. The voltage/current conversion circuit is configured to convert the phase compensated envelope voltage into an ET bias current.

Claim (Index 14):
The power amplifying device of  claim 13 , wherein the voltage/current conversion circuit comprises:\n a first V/I conversion circuit configured to convert a reference voltage into a DC current and adjust the DC current responsive to a third control signal; a second V/I conversion circuit configured to generate an ET current using the envelope signal and adjust the ET current responsive to a third control signal SC 3 ; and a bias current generating unit configured to generate the ET bias current based on the DC current and the ET current.
