Abstract

The design of a fifth-order 4-b quantizer single-loop ΣΔ modulator is presented that achieves 25-MS/s conversion rate with 84 dB of dynamic range and 82 dB of signal-to-noise ratio. Implemented in a 0.18-μm CMOS technology, the 0.95-mm² chip has a power consumption of 200 mW from a 1.8-V supply.
