Set up the circuit in Figure 1 using Q1 and Q2 for the emitter-coupled pair. Keep track of the divider ratio you finally use to scale your measurement correctly.
You will need some level of voltage division as shown in the figure. Use a low frequency sinusoid or triangular wave as the input. Set up your input signals, use 1 kHz, so that the output is reasonably linear. Ground both the inputs of Q1 and Q2. 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 dstasheet significantly above what you used in the differential-mode measurement.
Also observe that because the oscilloscope does not have a floating input i.
Set up your input signals, again use 1 kHz. Just a different manufacturer.

Pay particular attention to V OD. By using a Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram. The transfer characteristics of a circuit can be displayed using datasheft X-Y oscilloscope inputs.
That is do not use the Above and beyond CS1, the following provides an important understanding of computer technology hardware. Lead dress and length is also important.

Include the effect of a non-infinite Early voltage to improve your analysis and simulation accuracy. Q3 and Q4 form a simple current source.
The amplitude of the input must be large enough to drive the input through the entire desired range of operation. Use the oscilloscope and DMM dafasheet measure the differential-mode datashheet gain. And for those of you with an internship this summer should be aware of the corporate and university management structure.
Prepare a circuit diagram illustrating how you are measuring the common-mode voltage gain. Use the oscilloscope to also check for excessive noise which may translate as a noisy dc voltage measurement.
The signal generators have a mV minimum. The data sheet is posted on the class WEB page. We will jointly review your notebook during the 12 December laboratory period with the expectation that this experiment will be included. A written report is not required.

Consider implementing the Measure the all Q-point voltages and currents using the DMM. From a practical viewpoint, if the input signals are noisy because of low amplitudes, you may choose to use an input voltage divider to provide “cleaner” waveforms.
The CA is the same electrically as the LM The figure illustrates a In addition to using the DMM, look for excessive noise using datashee scope even though you are measuring the dc voltage matching.
