Hi All,

I have few queries regarding

Differential Amplifier Designing
--------------------------------

1. How do we decide which type of differential amplifier (PMOS diff.
ammp. or NMOS diff. amp.) is used for a particular Vref.

2. What is the significance of common mode range (the range in which
differential amplifier operates linearly ie. when transistors are in
saturation region). Is this range is required while designing a
differential amplifier. Does the selecion of differential amp.(PMOS or
NMOS) depends on it.

3. What are the main specifications required while designing a receiver
that uses a differential amplifier.

Thanks
Manoj
