Abstract
A linearizer comprises a delay compensation circuit, an envelope reshaping circuit and a phase shift unit. The delay compensation circuit is configured to delay an input signal and to output a delayed input signal to a power amplifier. The envelope reshaping circuit is configured to detect an envelope of the input signal and to generate a reshaped envelope signal. The phase shift unit configured to provide an envelope reshaped capacitance based on the reshaped envelope signal to the delayed input signal to reshape the delayed input signal.
