Uses CD4007A IC, having complementary ρair of opamps and inverter, to provide all circuits for AM broadcast radio capable of driving headphones or 8-ohm loudspeaker, Selectivity is provided by single tuned circuit and can be improved by optimizing value of C1 to adjust antenna loading. Tune with C3, adjusting L1 if necessary to get stations at low end of band. - C. Green, Easy-to-Build CMOS Radio Receiver, Modern Electronics, Sept. 1978, p 4-41, 46, and 59.
