Abstract
A traveling wave amplifier comprises a first normally off MOS transistor having a drain, source and gate terminal. The drain terminal is connected to a node of a drain line, which is connected to a first supply voltage potential via a connecting resistor. The gate terminal is connected to a node of a gate line, onto which an input signal is coupled. The source terminal is coupled to a second supply voltage potential via a first resistor. The traveling wave amplifier also comprises at least one second normally off MOS transistor. In addition, the traveling wave amplifier further comprises a normally off bias MOS transistor. The normally off bias MOS transistor forms a current mirror with at least one of the second normally off MOS transistors. An output signal of the traveling wave amplifier is tapped off on the drain line.
