Patent number: 8674867Abstract: The present disclosure relates to a device and method to increase the dynamic bit range of a radio-frequency digital-to-analog converter. A load of the Cap-RF-DAC typically consists of a transformer, which has a transfer ratio N:M derived by the number of windings of the primary and secondary coil, respectively. The load resistance can be varied by using switchable inductors on one or both sides of the transformer to vary an inductance of one of more sides of the switchable transformer, varying the transfer ratio of a transformer resulting in a switchable trans-impedance gain of the transformer. Switchable capacitor may also be configured in parallel to the switchable transformer to keep the load impedance constant while switching the switchable transformer.Type: GrantFiled: November 29, 2012Date of Patent: March 18, 2014Assignee: Intel Mobile Communications GmbHInventors: Bernd-Ulrich Klepser, Franz Kuttner
