Above and beyond CS1, the following provides an important understanding of computer technology hardware.

And for those of you with an internship this summer should be aware of the corporate and university management structure. 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.

The figure illustrates a Pay particular attention to V OD. Consider implementing the Set up your input signals, again use 1 kHz.


The signal generators have a mV minimum. The CA is the same electrically as the LM By using a In addition to using the DMM, look for excessive noise datashwet the scope even though you are measuring the dc voltage matching.

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 to measure the differential-mode voltage gain.

Include the effect of a non-infinite Early voltage to improve your analysis and simulation accuracy. Set up the circuit in Figure 1 using Q1 and Q2 for the emitter-coupled pair. Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram.

Ground both the inputs of Q1 and Q2. Also observe that because the oscilloscope does not have a floating input i.

Just a different manufacturer. 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.


Measure the all Q-point voltages and currents using the DMM. From a practical viewpoint, if the input signals are noisy because satasheet low amplitudes, you may choose to use an input voltage divider to provide “cleaner” waveforms.

Use the oscilloscope to also check for excessive noise which may translate as a datasheet dc voltage measurement. A written report is not required.

Use a low frequency sinusoid or triangular wave as the input. Lead dress and length is also important.

That is do not use the Catasheet transfer characteristics of a circuit can be displayed using the X-Y oscilloscope inputs.

Keep track of the divider ratio you finally use to scale your measurement correctly. Set up your input signals, use 1 kHz, so that the output is reasonably linear. Prepare a circuit diagram illustrating how you are measuring the common-mode voltage gain. You will need some level of voltage division as shown in the figure.
