A novel 900mV single-stage class-AB amplifier for the switched-OpAmp technique is presented. The Dynamic Current Source (DCS) circuit which boosts up the tail currents of the amplifier to improve the slew-limited characteristics is proposed. The tail current of the proposed circuit is well defined and independent from technology parameters and supply variations. The tail current of the amplifier is 40uA with zero differential voltages, while the maximum output current is nearly 900uA. A single-loop 3rd order ・メ-・ト modulator with the proposed amplifier is designed. For 245mV 15.625 kHz sinusoidal input signal, the simulated dynamic range of the modulator is 89dB. |
