i have some question about biasing the bjt into saturation, and its switch configuration
1. Is it necessary to have Vce <= 0.2 in order for bjt to saturate?
2. So what if a very low resistive load is connected to it, since I think usually it will then have Vce greater than 0.2, so that means bjt can never be saturated under low load condition?
3. is the switch configuration is just common emitter?
4. can I have the bjt as a switch in emitter follower?
your help will be greatly appreciated!
