title = "Wideband envelope elimination and restoration power amplifier with high efficiency wideband envelope amplifier for WLAN 802.11g applications",
abstract = "This paper presents the design of a silicon bipolar Class-E wideband envelope elimination and restoration (WBEER) power amplifier with a wideband high efficiency envelope amplifier. The envelope amplifier is composed of a linear op-amp stage and a switch buck converter, which achieves high fidelity and high efficiency amplification of wideband high peak to average (PAR) envelope signals. Experimental results show that the envelope amplifier has a bandwidth of 20MHz and 50-60% efficiency. An overall EER power added efficiency (PAE) of 28% at an output power of 19 dBm was achieved for a WLAN OFDM signal at 2.4GHz.",
