In order to increase the bandwidth of tuned amplifiers, one can use:1. Tuned circuit with inductance having high Q factor2. Double tuned amplifier with two tuned circuits coupled by mutual inductance3. Staggered tuned amplifiers in which different tuned circuits which are cascaded are tuned to slightly different frequencies
