Hello everybody,
I'm having trouble understanding the following example (from Microelectronic circuits, Sedra):
k'*(W/L)=1 [mA/V^2]
Vt=1V
Vdd=15V
This is the circuit (with established voltages and currents):

That's what written in the TB:
"Observe that the DC voltage at the drain (+10V) allows for a positive signal swing of +5V (i.e., up to Vdd) and a negative signal swing of -4V [i.e., down to (Vg-Vt)]."
I can't figure out how the negative signal swing is -4v? Maybe I'm interpreting this citation wrongly?
I found that the negative signal swing is -1.9V.
Here is my solution:
