Abstract
Two single-ended (S-E) and two fully-differential (F-D) band-pass filters are shown and compared in this contribution. Filters contain only simple current followers with multiple outputs and one current amplifier with digitally adjustable gain that is used to control the quality factor of each filter with direct or inverse proportion. Simulation results are included, and the values of quality factor obtained for each of the solutions are assessed.
