CircuitLab - Online Schematic Editor and Simulator

Draw and print beautiful schematics for lab reports. In-browser simulations make it easy to quickly learn electronics concepts. No need to Install, it is a Online Web Application !

CircuitLab - Online Schematic Editor & Simulator

Test and Simulate circuit ideas before breadboarding. SPICE-like models with a mixed-mode simulation engine help you apply one tool to a wide range of design tasks, from digital to analog, DC to VHF and beyond.

BJT Cascoded Active-load Differential Amplifier with CMFB

Build non-op-amp Common-Mode Feedback (CMFB) - This kind of high-gain differential input stage might be useful as part of an op-amp, but it's a bit silly to include an op-amp within a stage another op-amp......

Some Examples
  • 555 Timer as Oscillator / PWM Generator
  • 7805 & Wall-wart Experiencing Voltage Drop-out
  • Digital 4-bit counter and DAC
  • Diode full-wave (bridge) rectifier
  • Laplace transform step response and Bode plot
  • LED with resistor biasing
  • MOSFET switching inductive load
  • Op-Amp inverting / non-inverting amplifier
  • RLC resonance
  • Zener diode voltage reference

EDA and Product Design Ideas

Product Design Optimization - Some Ideas of mine that are decades old , related to EDA and Product Design.

Make Practical (it works), Affordable, Usable (ergonomics), Safe, Reliable (robust), Durable and Consistent, Maintainable (means servicing) Products.

Dust and Contamination in Connectors

Once i opened a RF Millivolt Meter of Marconi Instruments. It did not have a spec of dust inside, not even one micron size of dust particle.

Connectors exposed to Environment should not only be Corrosion resistant but also Dust, Grime & Insect Proof! Dummy Covers on exposed units.

Air Vents, Fans & Unused Slots in Modular Instruments. Missing Fasteners in cabinets, gaps in panel components collect Dust & Insects inside

Dust + Moisture + Smoke + Pollutants = Conductive Grime Deposits on PCB, Parts & in-between the IC pins. Can Simulation include this aspect.

Virtual Environmental Testing a part of simulation and EDA, just like Mechanical Modelling and Studying Thermal Gradients on PCB.

Labcenter Electronics - Proteus Design Suite

The Proteus Design Suite is wholly unique in offering the ability to co-simulate both high and low-level micro-controller code in the context of a mixed-mode SPICE circuit simulation. With this Virtual System Modelling facility, you can transform your product design cycle, reaping huge rewards in terms of reduced time to market and lower costs of development.

Labcenter Electronics - Proteus Design Suite

Co-simulation of microprocessor software within a mixed mode SPICE simulator.
  • Available for PIC, 8051, AVR, HC11, ARM7/LPC2000 and Basic Stamp processors
  • See your code interact with simulated hardware in real-time.
  • Interactive peripheral models for displays, keypads, etc.
  • Over 8000 analogue and digital device models.
  • Extensive single step and debugging facilities including system wide diagnostics.
  • Works with popular compilers and assemblers.

Labcenter Electronics - Proteus Design Suite

Proteus Virtual System Modelling (VSM) combines mixed mode SPICE circuit simulation, animated components and microprocessor models to facilitate co-simulation of complete microcontroller based designs. For the first time ever, it is possible to develop and test such designs before a physical prototype is constructed.

Design and Technology Site

This website contains numerous information sheets and exercises to enhance the study, understanding and teaching of DESIGN and TECHNOLOGY. - by V. Ryan

Design and Technology Site

The information sheets cover a wide range and include, the design process, gear systems, electronics, cams, printed circuit boards, PIC microcontrollers / computer control.

Topics - RoboLab, PCB Work, Computer Control, PIC Control, Product Design, Electronics, Design Process

Design and Technology Site

Potentiometers are used in circuits, when it is necessary to alter the resistance. Dark/light and temperature sensors usually have these components, as the potentiometer / variable resistor allows the circuit to be made more or less sensitive (they can be turned up or down - reducing or increasing resistance).

Capilano Computing - DesignWorks Schematic Capture

A well known firm in software tools for electronic design. Incorporated in 1982, Products Include Designworks Professional, DesignWorks Simulator and LogicWorks.

Capilano Computing - DesignWorks Schematic Capture

"DesignWorks Professional 5 doesn't just provide an environment for a single goal. It allows you to recapture your investment dollars by being flexible enough to handle all your design goals, be the goal a PCB design, Spice analysis, or simulation. You are not locked in to one PCB or simulation vendor."

LogicWorks 5

What is LogicWorks 5 

LogicWorks is an interactive circuit design tool intended for teaching and learning digital logic. No other software tool makes digital design easier, faster or more interactive than LogicWorks. The package gives you the power, speed and flexibility to create and test an unlimited number of circuit elements on-screen.

New in LogicWorks 5 for Windows is the ability to use a subset of the standard VHDL language to describe and simulate circuits. Hardware designs can freely mix devices and circuits described as schematic diagrams with blocks described textually using VHDL. See our VHDL page for a description of the language implementation in this version.
