Abstract: An information carrier contains a storage unit, an integrated circuit and a first and a second coupling element. The coupling elements are intermediate in the transfer of data, and energy from a base station to the integrated circuit, and vice versa. Between the base station and the coupling elements, the transfer of data and energy is contactless, such as by capacitive coupling. Between at least the first and/or both of the coupling elements, data and energy are transferred by the of capacitive coupling. The base station may be in an apparatus containing a reading device of the storage unit. To facilitate the capacitive coupling, the base station contains first and second capacitor plates. The information carrier and the apparatus with the base station containing said capacitor plates together constitute the system, which is suitable for copy protection of the information on the storage unit.

The identification transponder comprises an identification code generator, a rectifier; and a load transistor.

The control means (40) are arranged for operatively controlling the switching means (S1, S2, S3) for transferring electrical energy to a first output (Vout1) of the DC/DC converter (30) in a down-conversion mode and for transferring electrical energy from the first output (Vout1) to a second output (Vout2) of the DC/DC converter (30) in an up-conversion mode.

Abstract: An identification transponder (IDT) for transferring an identification code (IDC) to a base station (BS) by means of varying an RF-signal transmitted by the base station (BS) in a rhythm which corresponds to the identification code (IDC). The identification transponder (IDT) comprises means (IDCG) for the generation of the identification code (IDC); rectifying means (RTF); and a load transistor (TL). The load transistor (TL) is arranged in such a manner that it performs two tasks: the task of rectifying the RF-signal (thus it substitutes a diode function in the rectifying means (RTF)), and the task of supplying a variable load to the rectifying means (RTF). The variable load varies in said rhythm. As a consequence the input current of the rectifying means (RTF) is varied in said rhythm which in turn varies the RF-signal. This variation in the RF-signal is detected in the base station (BS).

Abstract: The information carrier (1) contains a storage unit (9), an integrated circuit (10) and a first and a second coupling element (31,32). Said coupling elements (31,32) are intermediate in the transfer of data and energy from a base station (50) to the integrated circuit (10) and vice versa. Between the base station (50) and said coupling elements (31,32) the transfer of data and energy is contactless, and preferably by capacitive coupling. Between at least the first (31) of and preferably both of the coupling elements (31,32) data and energy are transferred by means of capacitive coupling. The base station (50) is preferably incorporated in an apparatus (40) further containing the reading device (60) of the storage unit (9). To facilitate the capacitive coupling, the base station (50) contains a first and a second capacitor plate (54,55).

Abstract: The integrated circuit (1) suppresses leakage currents, which usually take place between neighboring transistors (10, 20) through the unpatterned semiconductor layer (5). In its first layer (3), the circuit (10) comprises electrically conductive tracks (4) which are in contact with the semiconductor layer (5), some of which tracks (4) are in use as source and drain electrodes (14, 15, 24, 25) and are preferably fork-shaped and interdigitated. The suppression of leakage currents is achieved by putting neighboring electrodes (14, 24) in different transistors (10, 20) at the same voltage and by excluding the presence of any other electrically conductive tracks between those neighboring electrodes (14, 24). Interconnect lines (39) carrying input or output signals are positioned in a second layer (7) as much as possible, which second layer (7) comprises electrically conductive tracks (8) and is not in contact with the semiconductor layer (5).

Abstract: A new integrated circuit in which bias currents are supplied by means of a current injector, a multi-layer structure in which current is supplied, by means of injection and collection of charge carriers via rectifying junctions, to zones to be biased of circuit elements of the circuit, preferably in the form of charge carriers which are collected by the zones to be biased themselves from one of the layers of the current injector. By means of said current injector circuit arrangements can be realized without load resistors being necessary, while the wiring pattern may be very simple and the packing density of the circuit elements may be very high. In addition a simple method of manufacturing with comparatively few operations can in many cases be used in particular upon application of transistors having a structure which is inverted relative to the conventional structure.
