- 9Show the effect of increasing feedback factor on a bode plot of closed loop gain vs frequency
- 10Open loop gain of this common gate amplifier
- 11Input resistance of a feedback network circuit
- 12Output impedance of a feedback network circuitNote: R_D in this case was open loop output impedance
- 13Positive feedback closed loop gain
- 14What is the procedure for determining loop stability?1. Calculate loop gain LG(s) = β * HOL(s)
