Abstract—A multiband flexible RF-sampling receiver aimed
at software-defined radio is presented. The wideband RF sam-
pling function is enabled by a recently proposed discrete-time
mixing downconverter. This work exploits a voltage-sensing LNA
preceded by a tunable LC pre-filter with one external coil to
demonstrate an RF-sampling receiver with low noise figure (NF)
and high harm
