FILTER DEVICE USING CHARGE TRANSFER IN A SEMICONDUCTOR

FILTER DEVICE USING CHARGE TRANSFER IN A SEMICONDUCTOR

Two analog filters of the second order are arranged in series with a transverse charge transfer filter upstream and downstream of the latter. The analog filters are switched capacitor filters having an amplifier and a network of capacitors and MOS transistors. The filtering device is entirely integr...

Zusammenfassung:Two analog filters of the second order are arranged in series with a transverse charge transfer filter upstream and downstream of the latter. The analog filters are switched capacitor filters having an amplifier and a network of capacitors and MOS transistors. The filtering device is entirely integrated onto the same semiconductor substrate.
