Patent number: 7469130Abstract: A polar modulator contains a first input for supplying an amplitude modulation word and a second input for supplying a phase modulation word. The first input is connected to a first signal path, and the second input is connected to a second signal path. The polar modulator contains a converter having a first input which is connected to a first signal path and having a second input which is connected to the second signal path. In this case, the converter is configured to output a radio-frequency signal derived from the phase modulation word and the amplitude modulation word. A feedback path has a level detector connected to the converter and has its output side connected to a correction device. The correction device is designed to output a correction word to the first signal path on the basis of a signal which is output by the level detector.Type: GrantFiled: October 21, 2005Date of Patent: December 23, 2008Assignee: Infineon Technologies AGInventors: Christian Mayer, José Pedro Diogo Faisca Moreira, Helmut Herrmann, Günter Märzinger

Patent number: 7391270Abstract: A phase locked loop is disclosed and includes a frequency divider circuit with a settable division ratio in a feedback path. The division ratio is produced using a control circuit which, besides an input for supplying the integer and fractional components for the frequency division ratio which is to be set, includes an input for supplying a phase correction signal. To produce the phase correction signal, the phase locked loop further includes a phase correction apparatus. The phase correction signal preferably contains a signal component with an exponential profile, and is supplied to the control circuit for producing a frequency division ratio for the frequency divider circuit such that it compensates for a phase drift in the output signal from the voltage controlled oscillator in the phase locked loop.Type: GrantFiled: March 22, 2005Date of Patent: June 24, 2008Assignee: Infineon Technologies AGInventors: Burkhard Neurauter, Günter Märzinger, Christian Münker, Roland Vuketich

Patent number: 7142070Abstract: A two-point modulator arrangement is specified, said arrangement being developed with respect to conventional two-point modulators to the effect that the high-pass coupling-in point of the modulator that comprises a phase locked loop is formed by an expanded loop filter. In accordance with the present principle, the expanded loop filter comprises a coupling-in element, at which the modulation signal is combined with the output signal of a phase comparator. A voltage-controlled oscillator having only one tuning input can thus advantageously be used.Type: GrantFiled: September 23, 2004Date of Patent: November 28, 2006Assignee: Infineon Technologies AGInventors: Stefan Herzinger, Günter Märzinger, Burkhard Neurauter, Robert Weigel
