It is always good practice to verify a circuit before using.
Switching-Mode Power Supplies are the most used circuits nowadays. But there are some difficulties with verifying their circuits: ...
An operational amplifier has the internal compensation circuit for stability which limits its working bandwidth. Frequency response of the compensated Op Amp has slope of −6 dB/octave or −20& ...
If you look through datasheets you will find a strange circuit used in front of some ADCs. It looks like a low-pass filter, but you will not find this topology in books.
Let’s try to figure out ...
The easiest way to build a driver with specified output impedance is to use an amplifier with high load compatibility and add a resistor to its output. The penalty is voltage drop across this ...
Common approach to build a third order low-pass filter is to use two circuit stages and two Op Amps. Making good One Op Amp design is not always easy, but it is possible.
Basic equations for ...
