This is a design laboratory involving operational amplifiers.Three separate circuits are to be designed, simulated and validated.
Prelab
Complete the table below using information from manufacturers’ published data. The middle
column is for parametric values; the right-hand column is for units (e.g., mV, nA, MHz). Note
whether values are typical or limiting (minimum or maximum) for each parameter.
Design and simulate a dc-coupled non-inverting amplifier circuit using one operational amplifier to
implement the function:
where Vin is the voltage at the input terminal and Vo is the voltage measured at the output terminal.
Both voltages are measured with respect to ground.
Start by 1 kohm at inverting input of opamp for input current control and vary feedback resistor to
obtain the desired gain. Use the signal generator to generate a 1mV pk_pk, 1kHz sinusoidal input to
your circuit.
Design your circuit using idealized resistors (assume exact values are available). Then modify your
design to use practical (available) resistor values. Your design is acceptable if the voltage gain of
the design using practical resistor values is falls into the range of 50V/V ± 5%. You are to use no
more than four resistors in the feedback network, and the ratio of the largest resistor to the smallest
resistor is not to exceed 15:1.
Show the schematic diagram of your practical design. Calculate the expected voltage gain and
bandwidth of your practical design. Enter your data in Table 2 below.
