Applying Effective Dynamic Frequency Scaling Method in Contactless Smart Card

A creative dynamic frequency scaling method in contactless smart card is presented for the first time. A low power magnetic field detection circuit, a simple load detection circuit, the quick load comparator and the simple clock switch scheme in the method are also presented. The test result shows t...
