Electronics Calculators

Basics

• Ohm's Law - V / I / R / P calculator
• Voltage Divider - Calculate output or find resistors
• RC Filter - Passive first-order LP/HP filters
• RL Filter - Passive first-order LP/HP filters
• LC Resonance - Resonant frequency of a tank circuit
• Pi Attenuator - Symmetrical RF attenuator
• LED Resistor - Current limiting resistor

Transistor Amplifiers

• CE Amplifier
• Emitter Follower
• CE + Emitter Follower - Two-stage with direct coupling
• Class A Power Amp - Single-ended with thermal analysis
• Class B Power Amp - Push-pull complementary pair
• Class AB Power Amp - Push-pull with Vbe multiplier bias

Op-Amp Circuits

• Inverting Op-Amp
• Non-Inverting Op-Amp
• Sallen-Key Filter
• Diode Clipper - Feedback and shunt clipping with real diode models

Utilities

• Frequency / Period / Wavelength - Conversion and wave parameters
• Voltage Converter - Vpp / Vpeak / Vrms
• dB Converter - dBV / dBu / dBm + audio levels guide
• Capacitor Code - 3-digit code ↔ value
• Resistor Color Code - 4/5-band color ↔ value
