I am looking for a receiver circuit in vhf band 108-118Mhz with AM modulation ,if there is any person who has worked in this field ,I would be grateful if he or she inform me.
You shouldn't use a superregen for listening to aircraft band!, it will cause interference to the aircraft! - if you want to listen to aircraft band you should use a superhet.
Ramsey Electronics, among other suppliers, makes a kit for the aircraft band. Several editions of the ARRL Radio Amateur's Handbook have such a receiver described though what's decribed may be super-regen so the cautions offered by Nigel might apply.
