The signal generators have a mV minimum.

The CA is the same electrically as the LM Ground both the inputs of Q1 and Q2. The figure illustrates a Just a different manufacturer. 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.

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. Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram. That is do not use the By using a Also observe that because the oscilloscope does not have a floating input i.

Set up your input signals, again use 1 kHz. A written report is not required.

The data sheet is posted on the class WEB page. Use the oscilloscope and DMM to measure the differential-mode voltage gain. Q3 and Q4 form a simple current source. Set up your input signals, use 1 kHz, so that the output is reasonably linear. Measure the all Q-point voltages and currents using the DMM. llm3046

And for those of you with an internship this summer should be aware of the corporate and university management structure. Set up the circuit in Figure 1 using Q1 and Q2 for the emitter-coupled pair.

We will jointly review your notebook during the 12 December laboratory period with the expectation that this experiment will be included. Lead dress and length is also important. The amplitude of the input must be large enough to drive the input through the entire desired range of operation. The transfer characteristics of a circuit can be displayed using the X-Y oscilloscope inputs.

Consider implementing the You will need some level of voltage division as shown in the figure. Include the effect of a non-infinite Early voltage to improve your analysis and simulation accuracy.

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

Above and datasjeet CS1, the following provides an important understanding of computer technology hardware. Pay particular attention to V OD.

Use a low frequency sinusoid or triangular wave as the input.
