Output level of common-source amplifier with PMOS load
Stating why the open loop circuit does not have a well defined bias voltage at the output in my own way: the open loop circuit has a poorly defined output voltage because the output impedance is very ...

How to calculate the voltage gain of a circuit with P-MOS and N-MOS transistors?
There are two inverting stages. Ignoring rds, the gain of each stage is determined by gm times drain load.
The load in the 1st stage is a diode connected PMOS. First stage gain is Av1 = - gm1 * 1/gm2 ...

How to calculate the voltage gain of a circuit with P-MOS and N-MOS transistors?
See M2 & M3 form a current mirror -- M3's current is equal to M2. M2's current is equal to M1.
For your (homework ?) answer, be sure to include the polarity (+ or -) of the gain.

PMOS switch for protection
a PMOS turns on when Vgs<Vth
The definition of "turn-on" in the data sheet is usually something like 1-10μA of channel current. That's pretty far away from what is considered a turn-on ...

PMOS switch for protection
In these types of circuits, the MOSFET is "backwards" with respect to the source and drain so you have conduction through the body diode but also a low-resistance path around the body diode ...

How to choose the right PMOS for inrush limiting application
From the datasheet that you have added in the question, I pasted below a snapshot of the SOA graph.
At |VDS| of 500mV, safe operating current is 1A and your use-case is 3A. If I understand right, ...
