I am building a Wien bridge oscillator with automatic gain control(AGC) circuit. How to select the appropriate transistor as a voltage controlled resistor.
First of all out of BJT,MOSFET and JFET which one to select? Again how to decide the desired specification of that selected category of transistor
Lastly, can we exactly know the range of resistance which can be achieved by varying the voltage?
