Sammanfattning

This paper presents a multi-bit, continuous time delta-sigma modulator with 20 MHz bandwidth implemented in 65nm CMOS for cellular communication. The modulator features a third order, single loop filter and a 4-bit internal quantizer operating at 640 MHz. The DACs are resistive for lower thermal noise compared to the current-steering DACs and nonreturn-to-zero DAC pulse is used to reduce the clock jitter sensitivity. The measured prototype consumes 11mW from a 1.2 V power supply, and achieves an SNDR/SFDR of 63.5dB/76dB.
