摘要

提出了一种恒带宽开关电容可编程增益放大器(SC-PGA)。通过对SC-PGA采用自适应米勒补偿技术，我们的SC-PGA在各种增益条件下实现了低功耗和高线性度。采用0.18 μm CMOS工艺的布局后仿真结果表明，在12 V/V增益下，与未采用自适应米勒补偿技术的SC-PGA相比，功率效率提高了三倍，且性能没有下降。在3.3 V模拟电压和1.8 V数字电源电压下，功耗为2.8 mW。

A constant bandwidth switched-capacitor programmable-gain amplifier utilizing adaptive miller compensation technique

This paper presents a constant bandwidth switched-capacitor programmable-gain amplifier (SC-PGA). By using an adaptive Miller compensation technique for the SC-PGA, our SC-PGA achieves low power consumption and high linearity at various gain conditions. The post-layout simulation results with 0.18 μm CMOS process show that power efficiency is tripled over the SC-PGA without the adaptive Miller compensation technique at 12 V/V gain without degrading performance. Power consumption is 2.8 mW at 3.3 V analog and 1.8 V digital supply voltage.
