Lab- Comparator Simulation Using OrCad Capture and Pspice

Lab- Comparator Simulation Using OrCad Capture and Pspice - Circuit Diagram

 

Transient Analysis:
Apply a sinusoidal input at Vin1 (high) of amplitude A (V) and offset B (V) at 1-kHz while applying the reference voltage C (V) at the second input Vin2 (low).

 

Parts:
MbreakN: NMOS input pair (W, L)
MbreakP: PMOS current source loads (W, L)
MbreakN: NMOS pair for current mirror (W, L)
IDC: Reference current (Value 1uA)
VDC: Supply voltage (Value 3V)
VDC: Vin2 (Value)
VSIN: Vin1 (Amplitude, Offset, Frequency)

 

Threshold Voltage:

  •  Select the transistor
  •  Right-click and select Edit PSpice Model
  •  Add below for NMOS and PMOS transistors:
  1. model Mbreakn NMOS VTO=0.7
  2. model Mbreakp PMOS VTO=-0.8
  •  Save


 

Voltage Markers:
Add voltage markers at the input and output terminals.

 

Simulation profile setup:
Analysis Type: Time domain (Transient)
Run to time: 10ms
Maximum step size: 10ns


 

Report Preparations:
Copying schematic and waveforms to Word document:
Schematic window: Go to Edit -> Select All (Ctrl+A) then Edit -> Copy (Ctrl+C)
 Paste to Word document.

Simulation window: Go to Window -> Copy to clipboard.
 Paste to Word document.

 

Displaying lengths and widths of the transistors on the schematic.

  •  Right-click on the transistor and select Edit Part.
  •  Double-click on the symbol of the transistor in the newly opened window.
  •  In the User Properties dialogue box, double-click on W.
  •  In the Display Properties dialogue box, enter Value and select Name and Value under Display Format. Click Ok.
  •  Repeat the previous steps for L.
  •  Save.
