A Reconfigurable, Multichannel Quantized-Analog Transmitter With <-35 dB EVM and <-51 dBc ACLR in 22-nm FDSOI

Abstract

This letter presents a multichannel quantized analog transmitter to maintain the spectral purity of the analog systems while offering radio-frequency digital-to-analog converter flexibility. Consuming 275 mW power, it achieves an EVM of better than −35 dB with an ACLR1/2 of −51/−54 dBc for a 15 MHz 64-QAM signal at 9.4-dBm output power.
