  We propose a realization of the superconducting diode effect in flux biased
superconducting circuits of Josephson junctions. So far the observation of the
superconducting diode effect has been limited to rather exotic material
platforms. In theoretical proposals, it relied on a non-sinusoidal form of the
current phase relation of Josephson junctions. Here, we show how the diode
effect can be engineered in superconducting circuits without any such
requirements. The only necessary ingredients are standard sinusoidal Josephson
junctions and flux bias lines that are readily available in scalable industrial
silicon-chip based superconducting design processes.
