Abstract :
This paper presents a new digitally programmable UHF transconductor compatible with pure digital CMOS technologies. The idea consists of a programmable/tunable transconductor, based on a parallel connection of unit folded-cascode cells, which is used to implement a fully-balanced current-mode Gm-C integrator to operate over the 30 MHz-220 MHz range with 80 dB of dynamic range for 1% of THD.
