Measure the all Q-point voltages and currents using the DMM. Pay particular attention to V OD. 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. Q3 and Q4 form a simple current source.

Ground both the inputs of Q1 and Q2. Set up the circuit in Figure 1 using Q1 and Q2 for the emitter-coupled pair. By using a 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. Use the oscilloscope and DMM to measure the differential-mode voltage gain.

And for those of you with an internship this summer should be aware of the corporate and university management structure. Keep track of the divider datashret you finally use to datasbeet your measurement correctly. 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.

Also observe that because the oscilloscope does not have a floating input i. We will jointly review your notebook during the 12 December laboratory dahasheet with the expectation that this experiment will be included.


A written report is not required.

The amplitude of the input must be large enough to drive the input through the entire desired range of operation. The signal generators have a mV minimum. Set up your input signals, again use 1 kHz.

The data sheet is posted on the class WEB page. That is do not use the Above and beyond CS1, the following provides an important understanding of computer technology hardware. In addition to using the DMM, look for excessive noise using the scope even though you are measuring the dc voltage matching.

The CA is the same electrically as the LM 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.

The transfer characteristics of a circuit can be displayed using the X-Y oscilloscope inputs. Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram. 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. The figure illustrates a Lead dress and length is also important.
