Click on the components button to place the component on the table.
Make connections as per the circuit diagram.
Click on 'Check Connection' button to check connections. If correct, Click on 'Show output voltage' button to view output on DMM.
Calculate the inverting bias current using the formula:
IB1 = Vo/Rf
Click on 'Result' button and enter the claculated value.
Click on 'Reset' button and proceed in the same way to calculate the input bias current at non-inverting terminal.
Click on the component button to place the component on the table.
Make connections as per the circuit diagram.
Click on 'Check Connection' button to check connections. If correct, Click on 'Show output voltage' button to view output on DMM.
Calculate the non-inverting bias current using the formula:
IB2 = Vo/R1
Click on 'Result' button and enter the claculated value.
The input bias current IB hence, can be calculated using the formula:
IB = (IB1 + IB2)/2
where, IB1 has to be calculated from previous part.
Click on the component button to place the component on the table.
Make connections as per the circuit diagram.
Click on 'Check Connection button to check connections. If correct, Click on 'Show output voltage' button to view output on DMM.
Calculate the input offset current using the formula:
Iio = Vo/Rf
Click on 'Result' button and enter the claculated value.
Click on the component button to place the component on the table.
Make connections as per the circuit diagram.
Click on 'Check Connection' button to check connections. If correct, Click on 'Show output voltage' button to view output (Vo) on DMM.
Calculate the input offset voltage, Vio using the formula:
Vio = (Vo - IioRf)/(1+Rf/Ri)
Click on 'Result' button and enter the claculated value
Click on the component button to place the component on the table.
Make connections as per the circuit diagram.
The input signal* has to be taken from the red terminal of A.F. Oscillator while the other terminal has to be grounded.
Also, feed the input signal to channel CH1 of the C.R.O and the output from Op-Amp IC must be fed to the channel CH2.
Click on 'Check Connection' button to check connections. If correct, Click on 'Show output voltage' button to view output.
Increase the frequency of input signal using the dial** on A.F. Oscillator until output wave becomes triangular. This is the required frequency fmax in KHz.
Calculate the slew rate using the formula:
S.R. = 2πfmaxVm/106 V/μs
Click on 'Result' button and enter the calculated value.
*Amplitude of input signal 'Vm' is 3V. ** dial can be controlled through both mouse and keyboard.
Instructions button remain inactive until parameter selected.
