Abstract
A conversion circuit is disclosed. In one aspect, the conversion circuit includes a first input terminal for receiving a digital signal. The conversion circuit includes a second input terminal for receiving a bias voltage signal. The conversion circuit includes an output terminal for outputting a current. The conversion circuit includes a first and a second switch transistor connected to the first input terminal for receiving the digital signal. The conversion circuit includes a first and a second current source transistor connected to the second input terminal for receiving the bias voltage signal. The conversion circuit further includes a first branch, wherein the first switch transistor is connected to the output terminal via the first current source transistor. The conversion circuit further includes a second branch, wherein the second current source transistor is connected to the output terminal via the second switch transistor.
