Abstract
An on-chip active balun with good gain and phase mismatch performance of within O.5dB and 1 degree, respectively, is presented in this paper. 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.
