DC-DC regulator for envelope tracking applications in power amplifier
Submitted by: Alejandro Coron (acoron@live.com).
DC-DC converter for envelope amplification applications. The envelope signal must be amplified to be able to supply a power amplifier. It must also have a very quick response work and be able to operate in a wide range of frequencies. This project replaces the fixed DC supply voltage to the RF PA with a dynamic supply voltage. This solution proposes a switched mode power supply using the buck converter structure, but with improved result by the multi-phase output filter.
