Hi everyone,
I am new in this forum and into analogue IC design.
I am trying to analyse the following circuit:
**broken link removed**
But right now what is intriguing me is this bit:
**broken link removed**
Can you check if I have drew correctly where the current goes? (in green and red)
**broken link removed**
If I wanted to simulate separately this part of the circuit:
**broken link removed**
How can I lay down the circuit and adapt it? I did it this way, but I don't know if it is correct:
**broken link removed**
The current source is has to be like a vin source? It has to be a signal source and not a dc current source correct?
That said I would like to make a basic question. From what I can tell M13 e a common source, the M14 is a common drain configuration, right? (source follower).
If it is, let me do a comment. In school we learn that the common gate needs to have it's drain terminal connected to a ground signal, that is, a vdd point.
Now in this circuit we don't have a vdd point in the gate of M15, so how is supposed to be a ground signal and as well provide a bias voltage ou a supply voltage to it?
Regards.
