Abstract
Embodiments of the invention show a bias circuit for providing a biasing signal at a bias connection. The bias circuit includes a bias transistor and a feedback node, wherein the feedback node is coupled to a control terminal of the bias transistor via a first impedance element. The feedback node is furthermore coupled to the bias connection via a second impedance element. The control terminal of the bias transistor is coupled to the bias connection via a bypass-coupling path, which bypasses the first impedance element and the second impedance element, such that there is a feedback path via the bypass-coupling path and via the bias transistor from the bias connection to the feedback node.
