Design radio receiver

[danut1234]

I search for someone good at FM receivers, i want to build a small FM radio receiver and i want a schematic that works at 1.5 volt, and was already made by some forum member. The idea is that i want to be very small . If you have already build it, i want to buy it from you. Please send me a message if you have something interesting , or you have an idea... Thanks, Dan

Silicon Labs has complete radio receivers in small packages.

well those FM IC are nice, but the minimum voltage is 2.7 volt, and I need 1.2-1.5 volt

A step-up converter can bring your 1.2 - 1.5V up to the desired 3.3V.

Sony has an AM/FM radio chip that is running on 1.5V, the CXA1129, they also made a radio with it.
It well documented here, even with paper on the chip by their designers: https://earmark.net/gesr/srf59.htm
