Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...

In a world of digital electronics, there are still necessary functions for analog circuits, especially filters. When real-world signals are digitized or synthesized, for example, analog filters are ...

Analog filters implemented in CMOS technology continue to be a cornerstone in the development of modern electronic systems. By integrating active components such as operational transconductance ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...
