Circuit arrangement for contactless chip card has charge pump circuit with amplifier stages with pump nodes, charge reservoir circuit with coupling nodes coupled pump nodes

摘要

The circuit arrangement has a first charge pump circuit with a first amplifier stage with a first pump node, a second amplifier stage with a second pump node and a charge reservoir circuit with a first coupling node coupled to the first pump node and a second coupling code coupled to the second pump node. The pump nodes store excess charge carrier. AN Independent claim is also included for the following: a contactless chip card with an inventive circuit arrangement.
