Abstract
Many kinds of filters are found in electronic circuits and provide a range of signal processing applications. Such filters can be passive, active, analog or digital and work across a range of frequencies. Present techniques provide an electronic filter circuit comprising resistive and capacitive elements, wherein a resistive element of the filter circuit is provided by a correlated electron material device.
