Flip-Flop

Monday, January 26, 2015 13

In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information. A flip-flop is a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs.

Step 1: Circuit Creation with Capture

• Create a new Analog, mixed AD project

• Place circuit parts • Connect the parts • Specify values and names • Name nodes

Step 2: Specify type of simulation • Create a simulation profile • Select type of analysis:

o Bias, DC sweep, Transient, AC sweep

• Run PSpice

Step 3: View the results • Add traces to the probe window • Use cursors to analyze waveforms • Check the output file, if needed • Save or print the results
