Our fundamental passive and inherently analog components – resistors, capacitors, and inductors – are so conceptually simple and easy to describe that we often don’t fully articulate or appreciate the many roles each can play in a system or circuit...

Integrating ADCs that provide accurate results without requiring a precision integrator capacitor has been around for a long time. A venerable example is that multimeter favorite, the dual-slope ADC...

ROHM has developed a new lineup of high accuracy current sense amps – the BD1423xFVJ-C and the BD1422xG-C. They are qualified under the AEC-Q100 automotive reliability standard...

Industrial-control circuits often derive their power from widely varying sources that can exceed the 40 V maximum rating of popular switching ICs...

Analog designers often need matched resistors for their circuits. The best solution is to buy integrated resistor networks, but what can you do if the parts vendors do not offer the desired values or matching grade?...

The 16-bit DACs are a de facto standard for high DC accuracy and precision domain conversion, but surprisingly few are fully 16-bit (0.0015%) precise...

Stephen Woodward’s DI, “Flip ON Flop OFF” does a wonderful job for DC voltages. I thought of extending this idea to much-needed AC voltages...

Toshiba Electronics Europe starts sample shipment for the TB9M001FTG, the second product in the innovative Smart Motor Control Driver series...

I recently published a Design Idea showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface PWM to switching regulators”...

PWM is a simple, cool, cheap, cheerful, and (therefore) popular DAC technology. Excellent differential nonlinearity (DNL) and monotonicity are virtually guaranteed by PWM...
