Abstract :
An on-chip active balun with gain and phase mismatch within 0.5 dB and 1 degree, respectively, integrated with a gain controllability feature, is presented. Applicable for direct conversion receiver circuits, the balun has been designed to operate in the 5-6 GHz range with a bandwidth of 400 MHz. With an output P1dB of -14.4 dBm, it is capable of being used as an independent amplifier in addition to acting as an active balun.
