Envelope tracking is a power supply technique that is used to adjust the converter voltage to improve the efficiency of a power amplifier, which is used in wireless systems. In envelope tracking technique, RF signal’s amplitude envelope is tracked and the bias voltage is adjusted according to the results in amplitude. This helps in operating power amplifier with maximum efficiency at any instantaneous power level. The recent cellular communications, such as W-CDMA, HSPA+, and LTE, operate signal waveforms with more extreme “peaks” and “valleys”, unlike GSM, which maintains continuous waveform throughout the operation. Recent cellular technologies experience continuous deflection in waveforms; hence, the requirement of envelope tracking technique is required to bring out maximum efficiency.
