hey all
last days i tried to build ASK (Sender/Reciever) module but i faced some difficulties in understanding the reciever unit.
i need small signal Analysis for the first stage (Tuned Common Base Amplifier) as in the schematic below(Av, Rin,Ro )
This is a super-regenerative receiver where Q1 is in the same time an amplifier and also a common-base LC oscillator, where C6 is used as a feedback network, C3 is an RF decoupling capacitor, and L1 is an RF choke.
