Overview

Low-pass filter (LPF) is the 4th order Butterworth filter with cut-off frequency adjustment. There are two modes for cut-off frequency programming: manually or automatically. In automatic mode one of the circuits is used in an oscillator mode therewith the oscillation frequency correlates with the LPF frequency. High third-order input intercept point is reached due to using a pseudodifferential circuit and Sallen-Key circuit.

Understanding cascaded integrator-comb filters

The previously obscure CIC filter is now vital to many high-volume wireless communications tasks and equipment. Using CIC filters can cut costs, improve reliability, and help performance. Here's a primer to get you started.

Revisiting the analogue video decoder: Brushing up on your comb filters

With such a large number of video decoders in the market it might seem an unnecessary indulgence to spend time looking again at the design of this fundamental but apparently obsolete building block, and certainly new designs are not appearing on the market and haven't done so for three or four years.

Ensuring reliability in Advanced IC design

To complete our task as engineers we rely on the tools we use. We collaborated with Siemens EDA solutions back in 2025 on a webinar about how we use their tools to develop our designs and layouts.
