Adjustable delayer, method for delaying an input signal and polar transmitter
Abstract:
An adjustable delayer for adjustably delaying an input signal based on a delay adjustment input information describing a desired delay includes a plurality of series-connected tunable delay circuits, wherein a first of the tunable delay circuits is configured to receive the input signal. The adjustable delayer also includes a closed-loop control circuit configured to provide a first delay tuning information to tune a combined delay of the plurality of tunable delay circuits to fulfill a predetermined condition. The adjustable delayer also includes a combiner to combine the first delay tuning information with a second delay tuning information, that is based on the delay adjustment input information, to obtain a combined delay tuning information. The adjustable delayer is configured to tune a delay of one or more of the tunable delay circuits based on the combined delay tuning information. The adjustable delayer is configured to provide the output signal based on one or more signals present at outputs of one or more of the adjustable delay circuits.
