CONTACTLESS CARD CLAMP CIRCUITS THAT COMPENSATE FOR REGULATOR REFERENCE VOLTAGE FLUCTUATIONS |
摘要 |
A contactless card includes an inductive circuit configured to send and receive signals, a rectifier circuit coupled to the inductive circuit and configured to generate a DC voltage from an AC voltage generated by the inductive circuit, a clamp circuit configured to limit the DC voltage, a regulator circuit configured to regulate the DC voltage and a control circuit configured to selectively enable and disable the clamp circuit and the regulator circuit.
