A 0.9 V 58 μW 92 dB SNDR audio ΔΣ modulator is presented. Through combining the featured architecture with elaborately designed circuits, ultra-low-power operation is achieved. A power-efficient switched opamp (SO) with a new chopper stabilisation circuit for SO application is exploited to reduce power and minimise flicker noise. A novel data-weighted-averaging (DWA) technique is applied to sup press...
A 9μW 88dB dynamic range (DR) switched-opamp (SO) μμ modulator is presented. A new SO with a fully switched-off scheme is proposed, which results in a 50μ power saving and double figure-of-merit over the traditional structure. Also, a novel resonator is applied to realise a zero-optimising coefficient of 1/100 with 75μ power and 70μ area reduction compared with the conventional one.
