CMOS monostable in proteus simulation

In this article we will learn how to make CMOS monostable in proteus simulation.
In the last post we will learn how to make CD4009 as linear amplifier in proteus simulation. You can visit our website,
I hope you appreciate my work, let’s discuss about today’s project.

Components which we use in this project are listed below:

  1. Nor gate (4001)
  2. Capacitor (470n)
  3. Resistor (1M5)
  4. Diod (4148)
  5. Jumper wires

Diagram of this project is below:

Construction of CMOS monostable in proteus simulation

  • Connect one input of a NOR gate 1 to ground (GND). This input will be held low.
  • Connect the other input of the same NOR gate to a trigger source like switch and battery. This input will be your trigger input, which will initiate the pulse when brought high.
  • Connect the output of gate 1 to the input of another NOR gate. This connection will create a feedback loop.
  • Connect the output of Nor gate 2 with the –ve point of capacitor
  • Connect the +ve side of capacitor with the one side of resistor and +ve side of diod
  • Connect the other side of resistor and diod with VCC

Working of CMOS monostable in proteus simulation

A CMOS (Complementary Metal-Oxide-Semiconductor) monostable circuit, also known as a “one-shot” circuit, is a digital electronic circuit that produces a single pulse output in response to an external trigger or input signal. It’s commonly used in digital electronics for various applications, including debouncing switches, generating precise time delays, and pulse shaping.
