- 1Calculate Closed Loop Gain
- 2What is the limit as A approaches infinity for the closed loop gain?
- 3Draw gain system flow
- 4Loop gain equation
- 5Closed loop gain in terms of open loop gain and feedback factor
- 6If loop gain is large, what condition applies?If loop gain is large, closed loop gain is independent of open loop gain.
- 7Open loop gain in terms of DC gain
- 8Draw table for dc gain, bandwidth, and gain x bandwidth for open loop and closed loop circuits with one pole
- 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)
2. Determine loop gain unity gain frequency
3. Determine loop gain phase at unity gain frequency
4. Determine phase margin: PM = phase at unity gain frequency + 180
5. If PM > 0, loop is stable - 15Noise margin definition
