Patent number: 9007100Abstract: A high-side semiconductor-switch driving method includes generating power for controlling a high side semiconductor switch. The high side semiconductor switch has a control terminal and the power allows a current to flow into the control terminal of the high side semiconductor switch to switch the high side semiconductor switch. The voltage at the control terminal of the high side semiconductor switch is quantified. The power dependent on the voltage at the control terminal of the high side semiconductor switch is controlled so that the current provided is increased when the voltage at the control terminal indicates that the current is not sufficient to switch the high side semiconductor switch.Type: GrantFiled: September 24, 2014Date of Patent: April 14, 2015Assignee: Infineon Technologies Austria AGInventors: Michael Asam, Helmut Herrmann

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.
