1. A transceiver circuit comprising:
a digital baseband circuit configured to generate a digital input vector having a time-variant amplitude; and
a target voltage processing circuit configured to:
divide each of a plurality of voltage modulation intervals into a plurality of voltage modulation subintervals;
determine a respective one of a plurality of modulated target voltage indicators for each of the plurality of voltage modulation subintervals based on the time-variant amplitude of the digital input vector; and
generate a target voltage signal comprising the plurality of modulated target voltage indicators.
