An ultra-low-voltage VCO-based ΔΣ modulator using self-compensated current reference for variation tolerance
This paper introduces a voltage-controlled-oscillator-based (VCO-based) first-order delta-sigma (ΔΣ) modulator that uses a novel current reference to improve the robustness of the modulator at ultra-low operating voltages. The proposed current reference harnesses the difference in transistor charact...
