Most designers consider slowness in diodes to be an imperfection or a limitation. Why not take a more positive view of the situation? After all, a zener or an avalanche diode is no more than a diode with a limited breakdown voltage, and you can ...

The editors of EDN will tell you that the Design Ideas section is the most popular section of the website, this goes back to the print editions, where that was the first section that most if not all readers turned to first upon getting a new issue. ...

The design of a standard inverting integrator is simple when bipolar supplies are available, but it's cumbersome with a unipolar supply. To allow adequate headroom for the output, the circuit must be biased away from ground, often at half the ...

Known devices for taking the square root contain an operational amplifier and a multiplier connected in a feedback loop. The accuracy of these devices depends on the method of building the multiplier, with the most accurate using logarithm and ...

Every PWM DAC design needs analog filtering to separate the desired PWM duty-cycle-proportional DC component from unwanted AC ripple. The simplest of these is the basic RC low-pass filter, which gives a peak-to-peak ripple amplitude (for the worst ...

Although current mirrors and circuits such as the Howland current source are taught in analog circuit courses, a surprising number of engineers tend to think exclusively in terms of voltage when defining the output of precision analog circuitry. ...
