Abstract :
This current-mode continuous-time ΣΔ modulator achieves 84dB dynamic range. With a sampling frequency of 26MHz, the modulator consumes 5mW at 1.8V. The peak SNR is 79dB in 100kHz bandwidth. The Total Harmonic Distortion is -79dB for 25kHz input signal. The fully differential third order modulator is implemented in 0.18µm CMOS process with polysilicon n-well capacitors, and occupies 1.56mm2.
