摘要： A touch panel system that includes drivers for providing detection signals on a first plurality of electrodes of a touch panel where each detection signal includes one or more frequency signal components with each frequency signal component having a frequency and at least three phase offsets for at least one frequency of the frequency signal components. Each detection signal has a unique frequency-phase offset combination of the one or more frequency signal components. The unique combinations allow for the determination of a touch at specific locations on the panel by sensing signals on a second set of electrodes.

摘要： A low drop out, LDO, voltage regulator circuit (200, 300) is that includes a high gain amplifier (205, 305) configured to receive a current biasing signal and arranged to regulate the voltage supply signal and output a regulated voltage supply signal (225, 325). A regulation adjustment circuit (222) is operably coupled to an output of the high gain amplifier (205, 305) and includes a comparator (235, 245) configured to compare the output regulated voltage supply signal (225, 325) with a threshold, wherein an output of the comparator (235, 245) is configured to perform one of: (i) supply a dynamic current boost (212, 242) to the LDO current biasing signal, in response to the regulated voltage supply signal voltage dropping below the threshold; (ii) activate a dynamic current pull down circuit to reduce an over voltage output of the LDO voltage regulator circuit in response to the regulated voltage supply signal voltage exceeding the threshold.

摘要： An RF circuit and method for detecting the amount of phase shift applied to an RF signal. An RF heating apparatus including the RF circuit. The RF circuit includes a phase shifter operable to apply a phase shift to a reference signal to produce a phase shifted reference signal. The RF circuit also includes a phase detector operable to detect a phase difference between the phase shifted RF signal and the phase shifted reference signal. The phase detector has a reduced input range at a frequency of the phase shifted RF signal. The RF circuit further includes a controller operable to control the phase shifter to set the phase of the phase shifted reference signal so that the phase difference between the phase shifted RF signal and the phase shifted reference signal falls within the reduced input range of the phase detector.

摘要： An RF circuit for providing phase coherent signals, an RF heating apparatus comprising the RF circuit and a method for providing phase coherent signals in an RF circuit. The RF circuit has a first frequency synthesiser including a fractional-N phase locked loop and a second frequency synthesiser including an integer-N phase locked loop. An output of the first frequency synthesiser is connected to a phase frequency detector of the integer-N phase locked loop of the second frequency synthesiser via a synchronisation signal divider for distributing a synchronisation signal from the first frequency synthesiser to the second frequency synthesiser. The integer-N phase locked loop of the second frequency synthesiser comprises a frequency divider of the same modulus as the synchronisation signal divider.

摘要： A local oscillator signal generation circuit is presented. The circuit comprises: a delay device adapted to delay a data signal according to a control signal; a data flip-flop having the delayed data signal provided to its data input terminal and a reference clocking signal provided to its clock input terminal; and a control circuit adapted to generate first and second partially overlapping pulse windows from the delayed data signal and to generate a control signal based on the first and second partially overlapping pulse windows and the reference clocking signal. The control signal is provided to the delay device to control the amount by which the data signal is delayed so as to align the rising edges of the data signal and the reference clock signal. A local oscillator signal is derived from the output of the data flip-flop.
