Abstract:
An envelope tracking (ET) bias circuit includes an envelope tracking (ET) bias circuit includes an envelope detection circuit, an envelope amplifier circuit, and an envelope output circuit. The envelope detection circuit is configured to detect an envelope of an input signal, and output an envelope signal based on the detected envelope of the input signal. The envelope amplifier circuit is configured to differentially amplify the envelope signal in response to a first control signal and cancel a direct current (DC) offset of the envelope signal to output an amplified signal from which the DC offset is canceled. The envelope output circuit is configured to generate an ET bias current by selecting either one of a negative signal of the amplified signal and a positive signal of the amplified signal in response to a second control signal.

Claim (Index 21):
The envelope tracking bias circuit of  claim 19 , wherein the ET sourcing/sinking circuit comprises:\n an ET current generation circuit configured to convert a voltage selected by the selection circuit into an ET bias current and adjust the ET bias current in response to the second control signal; and a DC bias cancel circuit configured to convert the DC offset bias voltage into the ET bias current and cancel the direct current from the ET_bias current.
