Abstract
A phase shift circuit made from integrable semi-conductor elements. It comprises: a sampling stage formed by two MOS type transistors operating in phase opposition, which supply, from the input signal (S.sub.e), a sampled signal S.sub.ECH ; a first MOS type transistor which forms the phase shift element, receives signal S.sub.ECH on its gate and delivers two signals (S.sub.1 and S.sub.2), which are opposite in phase, at its drain and source respectively; two capacitors, which receive signals S.sub.1 and S.sub.2 respectively, and are associated with polarizing means containing MOS type transistors, which enable the original D.C. components of signals S.sub.1 and S.sub.2 to be replaced by the same D.C. component (V.sub.P).
