## What is Circuit Simulator bitGateLab?

Circuit Simulator bitGateLab is an electric circuits and analog electronics lab on your PC, phone or tablet: draw a circuit, measure it with multimeters and an oscilloscope, get its frequency response, turn it into block diagrams with the Laplace transform and build it on a 3D breadboard. Works offline, no account required.

DRAW AND SIMULATE
• DC, AC with phasors and time-domain transients, using modified nodal analysis (MNA), the same method SPICE uses.
• Resistors, potentiometers, capacitors, inductors, transformers, thermistors and LDRs.
• DC and AC voltage and current sources, a signal generator (sine, square, triangle and ramp) and dependent sources.
• Diodes, Zener, LED, Schottky, NPN and PNP BJTs, N- and P-channel MOSFETs, JFETs and op amps with supply rails.
• Undo and redo, copy and paste, rotate, replace components and node labels.

MEASURE LIKE IN THE LAB
• Voltmeter, ammeter, wattmeter and a multimeter-style probe on any node, pin or component.
• Multichannel oscilloscope with a trace of every signal over time.
• Bode plot (magnitude and phase) plus DC and frequency sweeps.

LAPLACE AND CONTROL
• Block diagrams: gain, H(s), integrator, differentiator, PID, delay, summing junction and saturation.
• Turn your circuit into blocks and get its transfer function H(s).
• Step response, poles and zeros, Bode plot and step-by-step diagram reduction.

3D BREADBOARD
• Your circuit builds itself on a breadboard with resistors, capacitors, transistors, sources and wires.
• Rotate, zoom and choose isometric, top, front or side view.

PRACTICE EXERCISES
• Generate fresh exercises on series-parallel simplification, mesh and nodal analysis, the Wheatstone bridge and AC RC, RL and RLC circuits.
• Each exercise comes with its circuit, a graded question and a step-by-step solution.

IMPORT AND EXPORT
• Open SPICE netlists (.cir, .sp, .net) from ngspice or LTspice, including model libraries, and Falstad circuits.
• Export to SPICE, Falstad and CircuiTikZ for your LaTeX documents, or as an image or PDF.

FREE AND PREMIUM
• Phone and tablet (Android and iOS): every feature free, with circuits of any size and with ads; Premium removes the ads.
• PC (Windows): free with circuits of up to 30 components (wires and grounds don't count); Premium removes the limit.
• Premium: a monthly or yearly subscription, or a one-time lifetime purchase.

FOR LEARNING AND TEACHING
• Designed as a companion to an electric circuits course: whatever you work out by hand, you can check in the simulator.
• Light and dark theme, European or American symbols.
• 45 languages.

PRIVACY
No account and no cloud: your circuits are saved only on your device.
