R 1 ‘s voltage drop limits the zener diode’s voltage value that the circuit measures. If R 1 ‘s value is 1Ω, then the voltage drop across it is insignificant and, in millivolts, is equal to the zener ...

And if you want to see a steering circuit made with conventional diodes then we’ve previously talked about [Fran]’s circuit using a 555 and a 4017B decade counter to make a display count down ...

We have seen, in the previous section, that we can get a pretty decent voltage reference using a biased Zener diode circuit for a relatively reasonable cost. However, in this modern age of single ...

Diodes whose reverse-breakdown characteristics are controlled precisely during manufacture are called as Zener diodes and are intended specifically for operation in the reverse breakdown mode ...
