Low-Power Differential Input to Single-Ended Output GaN RF-DAC for RF-Signal Generation

A low-power differential input to single-ended output digital-to-analog converter (DAC) is presented, which is capable of providing radio frequency (RF)-signals with a data rate of up to \mathrm {8~G} bit/s. A constant direct current (dc) current source is realized as a self-bootstrapping device in...
