CG Rf amplifier
Hi
Want to build this circuit but firstly want to calculate (from 50 MHz - 100 MHz), simulate and build the Rf amplifier Q1 (Drain terminated in a resistor).. Calculate s11, s21 then compare with simulation. No progress yet I have RF microelectronics by Behzad Razavi, the equation uses (a capacitance not........) Please kindly assist... Is trying to "understand" the amplifier like this, not a good point to take from the schematic? Thankss... |

Re: CG Rf amplifier
That being a suoer regenerative receiver with a common gate input amp, I wouldn't like to think how a simulator would handle it in reality as it is ALMOST/Is an oscillator.
