Abstract :
Current-copier circuits are used in the IC realization of a transistor-only second-order ΣΔ modulator fabricated in a 0.9-μm digital CMOS process. The 13-bit resolution and 12-bit full-scale linearity make the converter suitable for A/D conversion in high-performance telecommunications applications
