Original Signal

Consider the filter spec. of your design!

If you Double click the time-axis,




We can design our own Filter!

AC Sweep result You have to use DB marker to show AC Sweep result.



• Differential Input Pair

V 0.5CMV V

0.5CMV V

Design : 2. Operational Amplifier



• Differential Mode Gain (Adm)

Differential mode gain > 40 dB




• Output Impedance Simulation Setup

Part name : IAC

Use V marker(Not VDB marker)




• Power Consumption

With the current marker, a more accurate power explanation can be obtained.

P = I x 2.5V

Caution: It’s not Op-amp. It is just example to show you how to measure power consumption.

Grading Policy

• Filter Design with ideal Op-amp [10], Operational Amplifier [20] ,Filter Design with your Op-amp[20]

• A few students who achieve the best results will be asked to present their design in English(?) for extra points(+[5]) during a Zoom seesion

• All plots and set-ups I showed you in this lecture must be in your design report. And your design report must include the method of design each circuit to satisfy specification. Report must be written in English.

• Late penalty is -10 point per day.
