▸ HAND-AUTHORED BY ENGINEERS

S-001FUNDAMENTAL

2× RESISTOR · PASSIVE

VOLTAGE DIVIDER

The first circuit every engineer learns — and it's still inside everything from ADCs to bandgap references.

L1 · BEGINNERREAD ANALYSIS ▸

S-002FILTER

1ST-ORDER · PASSIVE

RC LOW-PASS FILTER

A resistor and a capacitor. That's the entire anti-aliasing front end of half the audio gear on Earth.

L1 · BEGINNERREAD ANALYSIS ▸

S-003ANALOG

TL072 · OP-AMP

INVERTING AMPLIFIER

Two resistors set the gain, the virtual ground does the work. The textbook op-amp configuration.

L1 · BEGINNERREAD ANALYSIS ▸

S-004AMP

2N3904 · BJT

COMMON-EMITTER AMP

The granddaddy of voltage gain. Bias it wrong and the transistor either saturates or just sits there.

L2 · INTERMEDIATEREAD ANALYSIS ▸

S-005TIMING

NE555 · TIMER

555 ASTABLE

Hans Camenzind's 1972 timer chip — still shipping a billion units a year, still teaching freshmen RC time constants.

L2 · INTERMEDIATEREAD ANALYSIS ▸

S-006OSCILLATOR

2× 2N3904 · DISCRETE

ASTABLE MULTIVIBRATOR

Two transistors cross-coupled through capacitors. Watch them fight forever — it's the simplest oscillator that ever worked.

L2 · INTERMEDIATEREAD ANALYSIS ▸

S-007POWER

4× MOSFET · MOTOR

H-BRIDGE DRIVER

Four switches arranged in an H. The reason your DC motor knows which way to spin — and the reason shoot-through kills FETs.

L3 · ADVANCEDREAD ANALYSIS ▸

S-008POWER

LM2596 · SMPS

BUCK CONVERTER

Step 12V down to 5V at 90%+ efficiency. The reason your laptop charger doesn't weigh five pounds.

L3 · ADVANCEDREAD ANALYSIS ▸

S-009OSCILLATOR

TL072 + LAMP AGC

WIEN-BRIDGE OSCILLATOR

Bill Hewlett's master's thesis. A pure sine wave from five parts — and a literal light bulb does the precision work.
