In Reply to: Request: very low power receiver/ AM detector posted by A.J. Kool - designer - on 03/23/00 at 3:48 AM:
A one-transistor regenerative detector will indeed be tricky to adjust. I used to experiment with just those kinds of circuits back when Raytheon's CK722 and CK768 germanium transistors were hot technology.
However, since 455 KHz is the intermediate frequency (IF) of standard AM radios, why not make an IF strip in accordance with vendor application notes? You should be able to get a highly repeatable design with the sensitivity you require.
Good luck.
