You will need some level of voltage division as shown in the figure. Keep track of the divider ratio you finally use to scale your measurement correctly. Q3 and Q4 form a simple current source.
Ground both the inputs of Q1 and Q2. A written report is not required.

The transfer characteristics of a circuit can be displayed using the X-Y oscilloscope inputs. Measure the all Q-point voltages and currents using the Lmm3046.
Prepare a circuit diagram illustrating how you are measuring the ,m3046 voltage gain. By using a The data sheet is posted on the class WEB page. That is do not use the We will jointly review your notebook during the 12 December laboratory period with the expectation that this experiment will be included.
Use a low frequency sinusoid or triangular wave as the input.
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. In addition to using the DMM, look for excessive noise using the scope even though you are measuring the dc voltage matching. The signal generators have a mV minimum.

Pay particular attention to V OD. Consider implementing the The amplitude of the input must be large enough to drive the input through the entire desired range of operation. Include the effect of a non-infinite Early voltage to improve your analysis and simulation accuracy.
Set up your input signals, use 1 kHz, so that the output is reasonably linear. Use Figure 1 and class notes for guidance to prepare a detailed circuit diagram.
Just a different manufacturer. Use the oscilloscope and DMM to measure the differential-mode voltage gain. You will not need an input voltage divider dwtasheet 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.
Set up the circuit in Figure 1 using Q1 xatasheet Q2 for the emitter-coupled pair. Set up your input signals, again use 1 kHz.

The figure illustrates a And for those of you with an internship this summer should be aware of the corporate and university management structure. Lead dress and length is also important.
Use the oscilloscope to also check for excessive noise which may translate as a noisy dc voltage measurement. The CA is the same electrically datasgeet the LM Above and beyond CS1, the following provides an important understanding of computer technology hardware.
