Abstract

See full text

The present disclosure relates to a direct digital radio frequency modulator that includes a plurality of input terminals arranged to receive a multi-bit digital signal, and a plurality of converter circuits. In one example, the converter circuits are arranged to receive at an input terminal one bit of the multi-bit digital signal and to provide at a converter circuit output terminal an analog signal in accordance to the one bit. In the present example, a converter circuit includes an input transistor arranged to receive the one bit for enabling the converter circuit to produce the analog signal, a current source transistor, an additional transistor in cascode to the current source transistor, and a frequency modulator output terminal connected to the output terminal of each converter circuit for providing an analog output signal.
