OpAmpIdeal (Ideal Operational Amplifier)

Symbol

Available in ADS

Parameters

Name

Description

Units

Default

Gain

Complex Voltage Gain, use x + j × y, polar(x,y), dbpolar(x,y)

None

100000

Z1

Input impedance, inverting terminal

 

 

Z2

Input impedance, non-inverting terminal

 

 

Z3

Output impedance

 

 

Z4

Leakage impedance, inverting to non-inverting terminal

 

 

Freq3db

Frequency at which gain magnitude is down by 3dB

 

 

Delay

Time delay associated with gain

sec

0

Range of Usage

by default:
Z1 = ∞
Z2 = ∞
Z3 = 0
Z4 = ∞
Freq3db = ∞

Notes/Equations


  1. where F is the simulation frequency
  2. OpAmpIdeal is a noiseless component.
  3. The recommendation is to use a Gain value no greater than 1e10, or 200 dB for practical purposes.
