You will need some level of voltage division as shown in the figure.

Consider implementing the Set up the circuit in Figure 1 using Q1 and Q2 for the emitter-coupled pair. The transfer characteristics of a circuit can be displayed using the X-Y oscilloscope inputs. Set up your input signals, use 1 kHz, so that the output is reasonably linear.

From a practical viewpoint, if the input signals are noisy because of low amplitudes, you may choose to use an input voltage divider datashset provide “cleaner” waveforms. A written report is not required.

The figure illustrates a The amplitude of the input must be large enough to drive the input through the entire desired range of operation. Also observe that because the darasheet does not have a floating input i. We will jointly review your notebook during the 12 December laboratory period with the expectation that this experiment will be included.

In addition to using the DMM, look for excessive noise using the scope even though you are measuring the dc voltage matching.

Above and beyond CS1, the following provides an important understanding of computer technology hardware. Measure the all Q-point voltages and currents using the DMM. Q3 and Q4 form a simple current source. Use the oscilloscope and DMM to measure the differential-mode voltage gain.

You will not need an input voltage divider because the Acm is low, Figure 3, because the common-mode voltage gain is sufficiently low that you will have to increase the input level significantly above what you used in the differential-mode measurement.

Ground both the inputs of Q1 and Q2. Prepare a circuit diagram illustrating how you are measuring the common-mode voltage gain. The CA is the same electrically as the LM Just a different manufacturer. Include the effect of a non-infinite Early voltage to improve your analysis and simulation accuracy. And for those of you with an internship this summer should be aware of the corporate and university management structure.

Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram. The data sheet is posted on the class WEB page.

Set up adtasheet input signals, again use 1 kHz. By using a Use the oscilloscope to also check for excessive noise which may translate as a noisy dc voltage measurement.

That is do not use the The signal generators have a mV minimum. Lead dress and length is also important.

Pay particular attention to V OD. Keep track of the divider ratio you finally use to scale your measurement correctly. Datasheeet a low frequency sinusoid or triangular wave as the input.
