Abstract
This paper presents a second-order bandpass-like RC ac- tive filter implemented in 1- pm-gate-length GaAs technology. This filter is designed in order 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.Keywords
