Applicable for direct conversion receiver circuits, the presented balun has been features reconfigurability in the form of controllable gain, designed to operate in the 5-6GHz range with a bandwidth of 400MHz, With good linearity, input/output matching and gain and with improvement in noise performance, the proposed active balun circuit could effectively be used as the first stage of an RF front end replacing the LNA. © 2005 IEEE.en-USBalun circuits; Gain controllability; On-chip active balun; Receiver circuits; CMOS integrated circuits; Gain control; Optical character recognition; Microprocessor chipsA new 0.25um CMOS on-chip active balun with gain controllability for 5GHz DCRconference paper2-s2.0-27544486289http://ntur.lib.ntu.edu.tw/bitstream/246246/245571/-1/32.pdf
