1. Based on the results of Tables 19.5.4 and 19.5.8, do these circuits achieve a stable operating point when compared to beta?
2. Which circuit is more stable in this exercise; the emitter feedback bias or the collector feedback bias? Is it safe to say that this will always be the case for any emitter feedback bias circuit versus any collector feedback bias circuit?
3. Are the transistor voltages always as stable as the collector current or can they be more or less stable?
4. Based on the collector current equation derivations for the two circuits, derive the collector current equation for a combination circuit which consists of a collector feedback bias circuit with an emitter resistor added.
