Bjt diamond follower
WebOct 13, 2014 · The op must clearly have an emitter resistor given what he says for the current. Q1 is an emitter follower, so R3 is not needed. If you want to scale the design to use a higher voltage source ie 12v instead of 5 for example you would want to use PNP transistors for the high side switching and than you would need a base resistor. WebA BJT makes a good voltage follower as long as you remember that there is a 0.6V difference of input versus output. NPN BJTs lower the output voltage by about 0.6V, whereas PNP BJTs raise the output voltage by …
