Title:
DIRECT SAMPLING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2012/008106
Kind Code:
A1
Abstract:
Provided is a direct sampling circuit in which signal mixing between systems is avoided, even when signal systems in which time sharing is integrated are used together by time sharing. History capacitors (153, 155) are connected at a preceding step to a switched capacitor filter (160) for each system, buffer capacitors (173, 175) are connected at a subsequent step to the switched capacitor filter (160) for each system, and the history capacitors and buffer capacitors, which are connected to a rotation capacitor of the switched capacitor filter (160), are switched for each time-sharing system that is input.
