One or more systems, devices and/or methods of use provided herein relate to a device that can support a signal generation. A current-mode end-to-end signal path can include a digital to analog converter (DAC) operating in current-mode and an upconverting mixer, operating in current-mode and operatively coupled to the DAC. Analog inputs and outputs of the DAC and upconverting mixer can be represented as currents, and the DAC can generate a baseband signal. The DAC and upconverting mixer each can comprise switching transistors of the same type, such as p-type metal-oxide semiconductor (PMOS) switching transistors. In one or more embodiments, a current source and a diode-connected transistor can be arranged in parallel in the current-mode signal path, and the current source passes a static current, while the diode-connected transistor passes both a static current and a dynamic current.
