A single-loop third-order switched-capacitor sigma-delta modulator for hearing aid application is presented. Double-sampling is introduced to achieve a high performance with comparative low power consumption. The effect of capacitor mismatch is further discussed. To over come the switch-on problem under low-voltage, bootstrapping is adopted in this design. The modulator is implemented under SMIC 0...
The Hilbert-Huang transform (HHT) has the advantage in dealing with non-stationary signals, for its data driving. However there are some limitations of the original HHT. For getting more benefits in frequency resolution, an improved HHT is applied in this paper. In the improved version, the instantaneous harmonic retrieval method is applied to calculate the instantaneous frequencies of the intrinsic...
A 16bit audio SigmaDelta modulator is designed, with only 360 muw power dissipation under 0.9 V supply. A feedforward third-order single loop architecture is adopted to decrease the power dissipation. A novel double-boost switch is proposed in the design to decrease the on-resistance. A low power class-AB operational transconductance amplifier (OTA) with proposed self-adapted bias circuit is applied...
