Drawing Circuits with Capture CIS

• To simulate a circuit, we need to figure out the
  structure of the circuit. Capture CIS helps us to
  do that.
• Create a new project with Analog or Mixed A/D
  wizard after selecting a proper folder to save.
• Place the elements (even if it is the ground)
  that are in the PSpice libraries.
• Place the tags (if needed) that are in capsym.olb
  .

Bias Point Analysis with PSpice

• Where to find elements?
• Place ? Part or find the Place Part button on
  the toolbar
• Pick the element you want
• Click OK button
• How to link the elements?
• Find Place Wire button on the toolbar
• Link the elements you want
• NOTEwire crossing without big point ? openwire
  crossing with big point ? short

21
Place Wire
Pspice \ Creat Netlist to check the circuit is
right or not ?
22
Bias Point Analysis with PSpice

• IDC DC Current Source
• ISin Sinusoidal Wave Current Source
• IPULSE Square Wave Current Source
