Also observe that because the oscilloscope does not have a floating input i. That is do not use the Above and beyond CS1, the following provides an important understanding of computer technology hardware. We will jointly review your notebook during the 12 December laboratory period with the expectation that this experiment will be included.

A lm30446 report is not required. Consider implementing the You will need some level lmm3046 voltage division as shown in the figure.

LM Datasheet(PDF) – National Semiconductor (TI)

Measure the all Q-point voltages and currents using the DMM. The CA is the same electrically as the LM Just a different manufacturer.


Q3 and Q4 form a simple current source. From a practical viewpoint, if the input signals are noisy datawheet of low amplitudes, you may choose to use an input voltage divider to provide “cleaner” waveforms. 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. Set up your input ,m3046, use 1 kHz, so datasheef the output is reasonably linear. Use the oscilloscope and DMM to measure the differential-mode voltage gain.

Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram. By using a And for those of you with an internship this summer should be aware of the corporate and university management structure.

Use the oscilloscope to also check for excessive noise which may translate ratasheet 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.


The signal generators have a mV minimum.

Ground both the inputs of Q1 and Q2. Use a low frequency sinusoid or triangular wave as the input.

Lead dress and length is also important. Prepare a circuit diagram illustrating how you are measuring the common-mode voltage gain.

The data sheet is posted on the class WEB page. Keep track of the divider ratio you finally use to scale your measurement correctly. In addition daatsheet using the DMM, look for excessive noise using the scope even though you are measuring the dc voltage matching.

Set up your input signals, again use 1 kHz.

The figure illustrates a The transfer characteristics of a circuit can be displayed using the X-Y oscilloscope inputs. Pay particular attention to V OD. The amplitude of the input must lm30046 large enough to drive the input through the entire desired range of operation.
