Dear all, I simulated a radio-receiver circuit, where I have actually build a part of the circuit which helps to amplify a sine 550kHz frequency of microvolts (antenna voltage) into several volts, however, I do not see any amplification on the output as highlighted above where I attached a resistor in series with capacitor to act as a DC bias so that the voltage swings around 0V. I am not sure what have I done wrong and I have doubts regarding the use of the diode in this case because the forward voltage drop of diode is about 0.7V normally and this means we should be supplying several volts and not microvolts to the input of the diode. My question is how to amplify a sine 550kHz frequency of microvolts (antenna voltage) into several volts (preferably using transistors and not IC), I have attached my LT Spice file below for edit. I am sorry if this is a lousy circuit build by me but I just want to learn more
Thank you all for reading and have a nice weekend ahead
