A 5-MHz 11-bit delay-based self-oscillating ΣΔ modulator in 0.025 mm2

Bart De Vuyst and Pieter Rombouts UGent (2010) IEEE Custom Integrated Circuits Conference.
abstract
In this paper a self-oscillating Sigma Delta modulator is presented. By introducing this self-oscillation in the system, the loop filter operates at a speed significantly lower than dictated by the clock frequency. This allows for a simple and power efficient design of the opamps used in the loop filter. The self-oscillation is induced here by introducing a controlled delay in the feedback loop of the modulator. A second order CMOS prototype was constructed in a 0.18 um technology. A clock frequency of 850MHz generates a self-oscillation mode at 106.25 MHz. The modulator achieves a dynamic range (DR) of 66 dB for a signal bandwidth of 5 MHz. The power consumption is only 6mW and the chip area of the modulator core is 0.025mm^2.
