Summary:
A golden ratio analog to digital (A/D) converter (golden ratio encoder; GRE) was proposed as a special case of a bate-encoder, which encodes an analog signal to a digital bit-sequence with a real number radix of beta=phi (golden ratio). The beta-encoder family was mathematically proven to be robust against variations in circuit and environmental parameters, and noise, so that it is suitable for an integration with the latest ultra-small semiconductor process. This paper presents a proof-of-concept IC prototyping of the switched-current GRE A/D converter circuit using a 180 nm CMOS semiconductor process. Simulation results for the prototype circuit extracted from the layout are shown.
