A scheme of simple band-pass RC- and LR- filters on operational amplifiers containing only one capacitor or inductor and 3 resistors is proposed. A comparison is made of the amplitude-frequency ...

When we do textbook analysis, we tend to ignore the real-world concerns for the sake of learning. So, a typical theoretical voltage divider is simply two resistors. But if you examine a low-pass RC ...

Abstract: Based on TSMC 0.18μm 1P6M RF CMOS process, a 4th-order Butterworth analog low-pass filter (LPF) used in the transmitting link of 2.4GHz Wireless Sensor Network (WSN) radio frequency (RF) ...

People have asked for more information about analog and digital filters, so I'll devote a few columns to those topics. As taught to students in engineering schools, filters can seem like a math jungle ...
