🖥️ About These Simulators
Read firstEvery simulator below runs entirely in the browser — nothing to install and no live equipment involved. They're designed as drop-in demonstrations or student self-check activities for a solid-state devices or digital electronics unit. Click any card to launch the corresponding simulator page.
⚡ Foundations & Devices
Devices
Analog
Solid State Devices
Explore diode and bipolar-junction-transistor behavior — biasing regions, characteristic curves, and switching vs. amplification modes — with adjustable inputs and live output response.
⚠ Simulation only — no live equipment
Devices
Analog
Rectifiers
Compare half-wave and full-wave rectifier configurations and watch how each converts an AC input into pulsating DC, including the effect of filtering on output ripple.

🔁 Operational Amplifiers
Op-Amp
Core Concept
OP Amp Simulator
A general-purpose operational amplifier sandbox introducing open-loop gain, virtual short/ground concepts, and the ideal op-amp assumptions that every configuration below builds on.
⚠ Simulation only — no live equipment
Op-Amp
Configuration
Inverting Op-Amp Simulator
Adjust feedback and input resistor values to see how the inverting configuration sets closed-loop gain and produces an output that's 180° out of phase with the input.
⚠ Simulation only — no live equipment
Op-Amp
Configuration
Non-inverting Op-Amp Simulator
See how the non-inverting configuration amplifies a signal in phase with the input, and how gain is set purely by the ratio of the feedback network resistors.
⚠ Simulation only — no live equipment
Op-Amp
Configuration
Voltage Follower Op-Amp Simulator
Demonstrates unity-gain buffering — the output tracks the input exactly while the circuit provides high input impedance and low output impedance for stage isolation.
⚠ Simulation only — no live equipment
Op-Amp
Configuration
Comparator Op-Amp Simulator
Run the op-amp open-loop to compare two input voltages and watch the output swing rail-to-rail the instant one input crosses the other.
⚠ Simulation only — no live equipment
Op-Amp
Configuration
Integrator Op-Amp Simulator
Replace the feedback resistor with a capacitor and watch the output become the running time-integral of the input — the basis for ramp generators and analog computing stages.
⚠ Simulation only — no live equipment
Op-Amp
Configuration
Differential Op-Amp Simulator
Explore the differential amplifier configuration, which amplifies the voltage difference between two inputs while rejecting signals common to both — the building block of instrumentation amps.

🔢 Digital Logic & Timing
Digital
Combinational
Logic Gates
Toggle inputs on AND, OR, NOT, NAND, NOR, XOR, and XNOR gates and watch truth tables build live — a fast, visual way to reinforce Boolean logic fundamentals.
⚠ Simulation only — no live equipment
Digital
Sequential
Latches and Flip-Flops
Step through SR, D, and JK latches and flip-flops to see how clocked storage elements hold state between clock edges — the foundation of registers and counters.
⚠ Simulation only — no live equipment
Digital
Data Conversion
Multiplexers, Analog-to-Digital
Select among multiple inputs with a digital multiplexer, then see how an analog-to-digital converter samples and quantizes a continuous signal into discrete digital values.
⚠ Simulation only — no live equipment
Digital
Sequential
Timers and Counters
Configure a 555-style timer and binary/decade counters to explore pulse generation, timing intervals, and how counting circuits are built from cascaded flip-flops.
⚠ Simulation only — no live equipment
Digital
Control Systems
PLC Simulator
Program a virtual programmable logic controller using ladder logic rungs, wire up simulated inputs and outputs, and observe how industrial control logic drives real-world automation sequences.
