A notch for a narrow frequency band of a few per cent or even less normally requires close-tolerance components. At least, that’s what we thought until we came across a special opamp IC from Maxim. In ...
An array of electro-optical components fabricated as a silicon-based photonic IC provides narrowband passband and notch filtering above 10 GHz. How an electro-optic PIC can implement RF filtering ...
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 ...
