A high-selectivity continuous-time GaAs balanced filter

A second-order bandpasslike RC active filter implemented in 1- mu m-gate-length GaAs technology is presented. This filter is designed to achieve low sensitivity and high selectivity at the highest possible center frequency. Its quality factor can be tuned up to 20 or 30, using low-accuracy tuning biases, while its center frequency is tuned up to 1.6 GHz.<
