A $\beta$-encoder is a novel analog-to-digital converter with a real number radix of $\beta$, which is robust against variations in circuit and environmental parameters. A golden ratio encoder (GRE) is a special case of the $\beta$-encoder where $\beta=\phi$ (golden ratio). This paper presents a GRE circuit based on the switched-current circuit technique. The proper operation of the proposed circuit is confirmed through numerical and SPICE circuit simulations.
