Vorrichtung und Verfahren zur Gleichrichtung einer Eingangswechselspannung

DE 102008049648 A1 UPAB: 20100428 NOVELTY - The arrangement (400) has rectifier switches (402, 404) for supplying rectified voltages (Vb, Vdd) based on input alternating voltage. A transistor i.e. FET, acting as a diode has threshold voltage. A compensation circuit (406) arranged between an output of one of the switches and a control port of the transistor supplies compensation voltage to the control port such that current flow is provided between sink and source connections of the transistor with a voltage between the connections. The voltage is smaller than the threshold voltage. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a transponder comprising an antenna (2) a method for rectifying input alternating voltage. USE - Rectifier arrangement for use in a transponder (claimed). ADVANTAGE - The compensation circuit supplies the compensation voltage to the control port such that the current flow is provided between sink and source connections of the transistor with the voltage between the connections, thus enabling threshold compensation with stress intensification
