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 7):
A power amplifying device, comprising:\n a power amplifier configured to amplify a radio frequency (RF) signal; an envelope tracking (ET) current bias circuit configured to generate an ET bias current to provide the generated ET bias current to the power amplifier, and the ET current bias circuit comprising:\n a rectifying circuit configured to detect an envelope voltage from the RF signal; \n a phase compensation circuit configured to compensate for a phase of the envelope voltage in which the phase is delayed in the rectifying circuit to output a phase compensated enveloped voltage; and \n a voltage/current conversion circuit configured to convert the phase compensated envelope voltage input from the phase compensation circuit into an ET bias current; and \n a VCC circuit configured to generate a source voltage to provide the generated source voltage to the power amplifier.
