The mos parameter

Some important parameter are:

 n Cox  100 μA/V   2   pCox  30μA/V2

VTn  0.8V & VTp  1V     VA  10 V/ μ/

Exercise 1
For the current mirror
of figure below calculate:
1- Ro.
2- Vo-min
3- the condition for
having all transistor in
active region

3
Exercise 1 (cont.)

Design the circuit for Iin=Iout=10µA and Ib=1µA

Find a solution for having higher swing

4
Exercise 2
Designing a symmetrical amplifier with following
specifications:

GBW  1MHz with10pF load                 Vdd  5V

slew rate  1V/s

After design simulate your circuit and if necessary
apply the required modification
