I am trying to deliver .2A needed to the base of a 2n6059. My frequency generator TTL out only delivers between 66mA and .1A
I have a 680 ohm resistor before the base of the darlington to deliver the frequency.
The TTL impedance is 50 ohms.
How can I get the necessary current to the base of this darlington without changing the frequency. I could work around the frequency change with a counter and just adjust accordingly but id like to do it as cleanly as possible without distorting the waveform.
According to the data sheet Vce sat information you can use a minimum Beta (gain) of 100 to fully turn on the transistor. So just divide the transistor collector current by 100 to get the minimum required transistor base current.
Awesome... That's it? Change the resistor value? Will this effect frequency or waveform?
Sorry If I am asking dumb questions. This is My first real project.
