Abstract :
This paper presents a low-power CMOS ΣΔ modulator for a single-chip Bluetooth transceiver. It implements a low-power, fast-settling operational amplifier and can achieve 75 dB SNDR and 81 dB dynamic range over 1 MHz bandwidth. The design was fabricated using 0.18 μm CMOS process. The chip size is 0.63mm2 and the power dissipation is only 64 mW.
