hydra1664/RC-Low-Pass-Filter

This is a small personal project where I modelled a simple RC low-pass filter in LTSpice to find its cutoff (-3 dB) frequency. The aim was to verify the expected behaviour of the filter and compare ...

A 85/215/430 KHz 3 rd-Order Active-RC Low-Pass Filter with a Fast Automatic Frequency Tuning for a Zero-IF Receiver

Abstract: In this paper, a 3 rd order active-RC Low-Pass Filter (LPF) is proposed for a zero-IF receiver. The LPF enables 85/215/430 KHz passband selection and 3 dB per step gain adjustment from 0 to ...

How to Combine a Low-Pass Filter and an ADC Driver for a 20-Vp-p Signal

Driving an analog-to-digital converter (ADC) for optimum mixed-signal performance is a design challenge. Figure 1 shows a standard ADC driver circuit. During ADC acquisition time, the sampling ...
