Abstract

A detector circuit for determining an unknown load impedance (Z_x) without the need for a signal level detector is provided. The detector circuit comprises a phase detector to derive two phase differences (α, β) between three input signals (V₁₂, V₁₀, V₂₀) and a calculation circuit to derive a signal ratio.
