Integrated circuit for a transponder |
摘要 |
An integrated circuit is combined with a transponder to function either as a voltage or power supply for the transponder by extracting energy out of an electromagnetic field transmitted by a base station or as a detector in the transponder to act as a remote sensor. For this purpose the integrated circuit comprises diode rectifiers. Each of the diode rectifiers has a first and a second service terminal and a reference terminal. In order to reduce a parasitic impedance between the first service terminal and the reference terminal, the first service terminal of at least one rectifier diode is electrically connected to a reference potential such as ground. Parasitic diode characteristics are further reduced by surrounding the respective diode or diodes by an electrical conductor path also connected to the reference potential.
