Abstract
It is described a signal converter device (100) for converting a single-ended signal to a differential signal, the device (100) comprising: i) a multiplier device (110), configured to receive a single-ended incoming signal (105), and multiply the incoming signal (105) to provide a multiplied signal (115); and ii) a divider device (120), configured to receive the multiplied signal (115), and divide the multiplied signal (115) to provide a differential signal (125a, 125b). Further, a corresponding signal conversion method is described.

A signal converter device for converting a single-ended signal to a differential signal, the device comprising:
- a multiplier device, configured to
- receive a single-ended incoming signal, and
- multiply the incoming signal to provide a multiplied signal;
- a divider device, configured to
- receive the multiplied signal, and
- divide the multiplied signal—to provide a differential signal;
- a synchronizer device configured to
- provide a preset signal, and
- synchronize at least one of the multiplied signal and the differential signal with respect to the preset signal;
- and
- a combiner, coupled in between the multiplier device and the divider device;
- wherein the synchronizer device is configured to provide a synchronization signal to the combiner to generate a synchronized multiplied signal.
A method of converting a single-ended signal to a differential signal, the method comprising:
- receiving, by way of a multiplier device, a single-ended incoming signal by way of a multiplier device;
- multiplying, by way of the multiplier device, the incoming signal to provide a multiplied signal;
- subsequently dividing, by way of a divider device, the multiplied signal to provide a differential signal;
- synchronizing, by way of a synchronizer, at least one of the multiplied signal and the differential signal with respect to a preset signal;
- and
- generating, by way of a combiner coupled in between the multiplier device and the divider device, a synchronized multiplied signal.
