Penguat kelas AB satu peringkat 900 mV yang sesuai untuk teknik Opamp Bersuis dipersembahkan. Untuk menambah baik ciri-ciri terhad slew, litar Sumber Arus Dinamik (DCS) yang meningkatkan arus ekor penguat dicadangkan. Arus ekor litar yang dicadangkan ditakrifkan dengan baik dan bebas daripada parameter teknologi dan variasi bekalan. Arus ekor penguat ialah 40 µA dengan voltan pembezaan sifar, manakala arus keluaran maksimum adalah hampir 900 µA. Modulator Σ-Δ tertib ke-3 gelung tunggal dengan penguat yang dicadangkan telah direka bentuk. Untuk isyarat input sinusoidal 260 mV 15.625 kHz, julat dinamik simulasi modulator ialah 89 dB.

Abstract: A 900 mV single-stage class-AB amplifier suitable for the Switched-Opamp technique is presented. To improve the slew-limited characteristics, a Dynamic Current Source (DCS) circuit which boosts the tail currents of the amplifier is proposed. The tail current of the proposed circuit is well defined and independent of technology parameters and supply variations. The tail current of the amplifier is 40 µA with zero differential voltages, while the maximum output current is nearly 900 µA. A single-loop 3rd order Σ-Δ modulator with the proposed amplifier was designed. For a 260 mV 15.625 kHz sinusoidal input signal, the simulated dynamic range of the modulator is 89 dB.
