  1. Introduction to PSpice Digital Electronics LAB No.3 Engr. Mian Shahzad Iqbal Lecturer Department of Telecommunication Engineering

  2. SPICE • SPICE is a general-purpose circuit simulator capable of performing the following types of analysis

  3. Representation

  4. Dimension • Each element has a unit (dimension) which are as follows

  5. SPICE BASIC ELEMENTS • The basic elements of electronic circuits can be represented by the first letter

  6. Thevenin's Analysis • LAB N0.3 Thevenin's Analysis • VIN 1 0 DC 10V ; Voltage source of 10 V DC • IS 4 3 DC 2A ; Current source of 2 A DC • VX 4 5 DC 0V ; Measures the current through R5 • R1 1 2 5 • R2 2 3 10 • R3 2 0 20 • R4 3 4 40 • R5 5 0 10 • .TF V(2,4) VIN ; Transfer function analysis • .END ; End of circuit file

  7. Output • NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE • ( 1) 10.0000 ( 2) 12.5000 ( 3) 23.7500 ( 4) -11.2500 • ( 5) -11.2500 • VOLTAGE SOURCE CURRENTS • NAME CURRENT • VIN 5.000E-01 • VX -1.125E+00 • TOTAL POWER DISSIPATION -5.00E+00 WATTS • **** SMALL-SIGNAL CHARACTERISTICS • V(2,4)/VIN = 6.250E-01 • INPUT RESISTANCE AT VIN = 2.000E+01 • OUTPUT RESISTANCE AT V(2,4) = 1.094E+01
