A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Op amps are often used as drivers for ADCs to provide the gain and level-shifting required for the input signal to match the input range of the ADC. An op amp may be required because of the ...

How to decide between buffered and un-buffered (switched capacitor), high-speed analog-to-digital converters, with an example of anti-aliasing filter design. The fundamental end goal when using an ADC ...

All modern high speed ADCs need an input common mode voltage for their differential inputs that must fall within some acceptable range for correct operation. This is sometimes a trivial issue where ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...
