The time-interleaved ADC circuit comprises an input for an analog input signal, a first ADC bank comprising a first plurality of parallel time-multiplexed ADCs, wherein the first plurality of parallel time-multiplexed ADCs is configured to subsequently generate a first plurality of samples of the analog input signal during a first time interval, a first buffer amplifier coupled between the input and the first ADC bank. The time-interleaved ADC circuit further comprises a second ADC bank comprising a second plurality of parallel time-multiplexed ADCs, wherein the second plurality of parallel time-multiplexed ADCs is configured to subsequently generate a second plurality of samples of the analog input signal during a second time interval, wherein the first and the second time intervals are subsequent time intervals, a second buffer amplifier coupled between the input and the second ADC bank. The first ADC bank has associated therewith a first dummy sampler, wherein the ADC circuit is configured to activate the first dummy sampler before the start of the first time interval. The second ADC bank has associated therewith a second dummy sampler, wherein the ADC circuit is configured to activate the second dummy sampler before the start of the second time interval.

摘要： An example of a device for generating a broadband frequency signal comprises a first controlled oscillator, a second controlled oscillator, a phase-locked loop for feeding back an output signal of a controlled oscillator to the corresponding controlled oscillator, and a mixer. The mixer is configured to generate the broadband frequency signal by mixing an output signal of the first controlled oscillator and an output signal of the second controlled oscillator. The device may, for example, be realized by means of a single phase-locked loop. A further example relates to a device for generating a frequency signal with a controlled oscillator and a phase-locked loop with a further controlled oscillator and a mixer in the feedback path of the phase-locked loop. Examples further relate to a high-frequency device for emitting a high-frequency signal and a method for generating a broadband frequency signal.
