I am currently designing an AM radio. I am utilizing a diode demodulator
to extract the envelope of my carrier signal. I am using a 1N34A germanium diode, which has a forward voltage of 0.3 volts. I would like to know what are the constraints on the DC point at the input of the demodulator. I believe it is necessary to have an offset of 0 V so as to avoid following the input signal at the wrong moment, but I am not entirely sure. Could I benefit from a DC offset? I'm also wondering about the effects of loading on my demodulator, since I will be connecting a voltage amplifier stage before it. Thank you!
