I guess that's because all the grounded base circuits I've worked with had the base connected to GND or Vcc. I thought that blocking the supply on the right didn't make much sense as well.I think it's it. Feel free to change anything and give me some suggestions!
Please note that the input signal is DC (USB 5V source), not AC.
So, is there a way that I can use my USB port as an input (which is DC), and how much voltage should I apply as Vcc (on the left in my circuit)?Hello,
The circuit is a common base circuit.
The Base is AC grounded by the 1 uF capacitor.
I assume the 5 Volts source on the right is the signal input.
It will NOT amplify the DC voltage as shown.
It also will never reach 15 Volts on the output as the powesupply shown on the lefty is only 5 Volts.
