This paper presents a design of Q and center frequency tunable LC bandpass filter at 5.2GHz using 130nm CMOS technology. Centre frequency tuneability was achieved by implementing NMOS transistors biased as varactor. Q-factor enhancement and tuneability was achieved using the negative transconductanc...
