So I have an FM signal: 200 mVpp, 11.5 MHz carrier, max deviation - 500 kHz, modulating signal frequency range is 40-10000 Hz. And I need to demodulate it with lowest noise possible. The circuit has to be low voltage (3.3V or lower), low power and low profile (<4mm, so no fancy inductors and transformers). What are the best ways to do this?
I've found **broken link removed** circuit, it has super low power consumption, can be made in low profile and doesn't require much tuning, which is also great, but I'm not sure about it's noise performance. I also think about multiplying signal frequency 4-5 times with PT7C4511 clock multiplier and then demodulating it with TLC2933 PLL.
