I've been working with some BJT transistor constant current circuits and of these 4 basic designs I like the Zener option. Very simple to calculate and, to me, a pretty straight forward design. Are there any real benefits or pitfalls of using basic diodes or Zeners over a standard resistor voltage divider base bias? I also like the JFET options or using LM317s for higher currents...
