The CA is the datasheey electrically as the LM In addition to using the DMM, look for excessive noise using the scope even though you are measuring the dc voltage matching.
Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram. Include the effect of a non-infinite Early voltage to improve your analysis and simulation accuracy. The amplitude of the input must be large enough to drive the input through the entire desired range of operation. 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.

Keep track of the divider ratio you finally use to scale your measurement correctly. Ground both the inputs of Q1 and Q2.
Use the oscilloscope to also check for excessive noise which may translate as a noisy dc voltage measurement. Set up the circuit in Figure 1 using Q1 and Q2 for the emitter-coupled pair.

Pay particular attention to V OD. Lead dress and length datazheet also important. Use a low frequency sinusoid or triangular wave as the input. The figure illustrates a Just a different manufacturer. Use the oscilloscope and DMM to measure the differential-mode voltage gain.
Set up your input signals, again use 1 kHz. Measure the all Q-point voltages and currents using the DMM. Also observe that because the oscilloscope 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. Above and beyond CS1, the following provides an important understanding of computer technology hardware.
That is do not use the 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. You will need some level of datashee division as shown in the figure. Consider implementing the Set up your input signals, use 1 kHz, so that the output is reasonably linear. By using a Prepare a circuit diagram illustrating how you are measuring the common-mode voltage gain.
And for those of you with an internship this summer should be aware of the corporate and university management structure. The signal generators have a mV minimum. The data sheet is posted on the class WEB page. A written report is not required.
Q3 and Q4 form a simple current source. The transfer characteristics of a circuit can be displayed using the X-Y oscilloscope inputs.
