Title :
Analog sample-data filters
Abstract :
An analogue sample-data filter exactly equivalent, in the sample- data limit, to a simple RC low pass filter is demonstrated. The implementation requires only capacitors, MOSFETS, and a pulse generator. The filter time constant can be adjusted by changing the generator´s pulse rate. The basic concept is then extended to apply to high-pass and to very-high-Q bandpass filters.
